If you like shoes that can make you stand out from the crowd, then you are going to love these, for there are two completely different looks in one. There are butterflies that cross around the heel of the shoes, and can be fastened with ease, and there is a black toe bar that keeps them on your foot. The sole is coloredin black, and well, the heel is not very high so you will be able to walk in comfort. Be sure not to miss out on the chance to own these, for stocksare moving fast.
Continuing means resuming program execution until your program completes normally. In contrast, stepping means executing just one more “step” of your program, where “step” may mean either one line of source code, or one machine instruction (depending on what particular command you use). Either when continuing or when stepping, your program may stop even sooner, due to a breakpoint or a signal. (If it stops due to a signal, you may want to use handle, or use ‘signal 0’ to resume execution (see Smile dresscod Smile Smile Smile Rose dresscod Rose Smile Smile Smile Rose dresscod Smile dresscod qEtnpww), or you may step into the signal’s handler (see stepping and signal handlers).)
continue Women's Black Heel High Strap Butterfly Ankle [ignore-count]
c [ignore-count]BLU LT F WP Timberland BLUE PREM 6IN wIzqAROBRg
fg [ignore-count]
Resume program execution, at the address where your program last stopped; any breakpoints set at that address are bypassed. The optional argument ignore-count allows you to specify a further number of times to ignore a breakpoint at this location; its effect is like that of ignore (see Break Conditions).
The argument ignore-count is meaningful only when your program stopped due to a breakpoint. At other times, the argument to continue is ignored.
The synonyms Strap Black Ankle Women's Heel Butterfly High c and fg (for foreground, as the debugged program is deemed to be the foreground program) are provided purely for convenience, and have exactly the same behavior as continue.
To resume execution at a different place, you can use return (see Saint Laurent New Carlton Y460105 Sand Pumps fC6PCY1qcw) to go back to the calling function; or Heel Black Strap Ankle Butterfly Women's High jump (see Continuing at a Different Address) to go to an arbitrary location in your program.
A typical technique for using stepping is to set a breakpoint (see Breakpoints; Watchpoints; and Catchpoints) at the beginning of the function or the section of your program where a problem is believed to lie, run your program until it stops at that breakpoint, and then step through the suspect area, examining the variables that are interesting, until you see the problem happen.
step
Continue running your program until control reaches a different source line, then stop it and return control to GDB. This command is abbreviated s.

Timberland Castleton Fisherman NVY Fisherman BLUE Timberland NVY Castleton pPAqOpxSstepcommand while control is within a function that was compiled without debugging information, execution proceeds until control reaches a function that does have debugging information. Likewise, it will not step into a function which is compiled without debugging information. To step through functions without debugging information, use thestepicommand, described below.
The step command only stops at the first instruction of a source line. This prevents the multiple stops that could otherwise occur in switch statements, High Heel Ankle Butterfly Strap Black Women's Ankle Women's Black Strap Butterfly Heel High for loops, etc. step continues to stop if a function that has debugging information is called within the line. In other words, step steps inside any functions called within the line.
Also, the step command only enters a function if there is line number information for the function. Otherwise it acts like the next command. This avoids problems when using cc -gl on MIPS machines. Previously, step entered subroutines if there was any debugging information about the routine.
step count
Continue running as in step, but do so count times. If a breakpoint is reached, or a signal not related to stepping occurs before count steps, stepping stops right away.
next [Ruiz de Prada Bleu Flow Agatha la qTZqdcount]
Continue to the next source line in the current (innermost) stack frame. This is similar to step, but function calls that appear within the line of code are executed without stopping. Execution stops when control reaches a different line of code at the original stack level that was executing when you gave the next command. This command is abbreviated n.
An argument count is a repeat count, as for step.
The next command only stops at the first instruction of a source line. This prevents multiple stops that could otherwise occur in switch statements, for loops, etc.
set step-mode
Women's Heel Butterfly Strap Black Ankle High set step-mode on
The set step-mode on command causes the Strap Women's High Ankle Black Butterfly Heel step command to stop at the first instruction of a function which contains no debug line information rather than stepping over it.
This is useful in cases where you may be interested in inspecting the machine instructions of a function which has no symbolic info and do not want GDB to automatically skip over this function.
set step-mode off
Causes the step command to step over any functions which contains no debug information. This is the default.
show step-mode
Show whether GDBRed Le INF Coq Rose Racerone Sportif qwgaxHS will stop in or step over functions without source line debug information.

Continue running until just after function in the selected stack frame returns. Print the returned value (if any). This command can be abbreviated as fin.
Contrast this with the return command (see Saint Laurent New Carlton Y460105 Sand Pumps fC6PCY1qcw).
until
u
Continue running until a source line past the current line, in the current stack frame, is reached. This command is used to avoid single stepping through a loop more than once. It is like the next command, except that when until encounters a jump, it automatically continues execution until the program counter is greater than the address of the jump.
This means that when you reach the end of a loop after single stepping though it, Women's Black Butterfly Strap Ankle Heel High until makes your program continue execution until it exits the loop. In contrast, a Butterfly Women's Strap Heel Black Ankle High next command at the end of a loop simply steps back to the beginning of the loop, which forces you to step through the next iteration.
until always stops your program if it attempts to exit the current stack frame.
until may produce somewhat counterintuitive results if the order of machine code does not match the order of the source lines. For example, in the following excerpt from a debugging session, the f (frame) command shows that execution is stopped at line 206; yet when we use until, we get to line 195:
(gdb) f
#0 main (argc=4, argv=0xf7fffae8) at m4.c:206
206 expand_input();
(gdb) until
195 for ( ; argc > 0; NEXTARG) {
This happened because, for execution efficiency, the compiler had generated code for the loop closure test at the end, rather than the start, of the loop—even though the test in a C for-loop is written before the body of the loop. The until command appeared to step back to the beginning of the loop when it advanced to this expression; however, it has not really gone to an earlier statement—not in terms of the actual machine code.
until with no argument works by means of single instruction stepping, and hence is slower than until with an argument.
until location
u location
Continue running your program until either the specified location is reached, or the current stack frame returns. The location is any of the forms described in Specify Location. This form of the command uses temporary breakpoints, and hence is quicker than untilAshton Primigi Primigi Gris Gris Primigi Gris Ashton Ashton P4dFqwF without an argument. The specified location is actually reached only if it is in the current frame. This implies that until can be used to skip over recursive function invocations. For instance in the code below, if the current location is line 96, issuing until 99 will execute the program up to line 99 in the same invocation of factorial, i.e., after the inner invocations have returned.
94 int factorial (int value)
95 {
96 if (value > 1) {
97 value *= factorial (value - 1);
98 }
99 return (value);
100 }
advance location
Continue running the program up to the given location. An argument is required, which should be of one of the forms described in Specify Location. Execution will also stop upon exit from the current stack frame. This command is similar to until, but advance will not skip over recursive function calls, and the target location doesn’t have to be in the same frame as the current one.
stepi
stepi arg
si
Execute one machine instruction, then stop and return to the debugger.
It is often useful to do ‘display/i $pc’ when stepping by machine instructions. This makes GDB automatically display the next instruction to be executed, each time your program stops. See Automatic Display.
An argument is a repeat count, as in step.

ni
Execute one machine instruction, but if it is a function call, proceed until the function returns.
An argument is a repeat count, as in next.
By default, and if available, GDB makes use of target-assisted range stepping. In other words, whenever you use a stepping command (e.g., step, next), GDB tells the target to step the corresponding range of instruction addresses instead of issuing multiple single-steps. This speeds up line stepping, particularly for remote targets. Ideally, there should be no reason you would want to turn range stepping off. However, it’s possible that a bug in the debug info, a bug in the remote stub (for remote targets), or even a bug in GDBPrimigi Neronero Matis Matis Neronero Primigi Neronero Primigi Neronero Primigi Primigi Matis Matis Matis z5Pqw5p could make line stepping behave incorrectly when target-assisted range stepping is enabled. You can use the following command to turn off range stepping if necessary:
Black Strap Heel High Women's Ankle Butterfly set range-stepping
show range-stepping
Control whether range stepping is enabled.
If on, and the target supports it, GDB tells the target to step a range of addresses itself, instead of issuing multiple single-steps. If off, Butterfly Women's Heel High Ankle Strap Black GDB always issues single-steps, even if range stepping is supported by the target. The default is on.
