instead of stopping, it just decrements the ignore count by one and continues. As a
result, if the ignore count value is n, the breakpoint does not stop the next n times your
program reaches it.
ignore bnum count Set the ignore count of breakpoint number bnum to count.
The next count times the breakpoint is reached, your
program's execution does not stop; other than to decrement
the ignore count, GDB takes no action.
To make the breakpoint stop the next time it is reached,
specify a count of zero.
When you use continue to resume execution of your
program from a breakpoint, you can specify an ignore count
directly as an argument to continue, rather than using
ignore. See “Continuing and stepping” (page 64).
If a breakpoint has a positive ignore count and a condition,
the condition is not checked. Once the ignore count reaches
zero, GDB resumes checking the condition.
You could achieve the effect of the ignore count with a
condition such as '$foo-- <= 0' using a debugger
convenience variable that is decremented each time. See
“Convenience variables” (page 96).
Ignore counts apply to breakpoints, watchpoints, and catchpoints.
5.1.6 Breakpoint command lists
You can give any breakpoint (or watchpoint or catchpoint) a series of commands to
execute when your program stops due to that breakpoint. For example, you might
want to print the values of certain expressions, or enable other breakpoints.
commands [bnum], ...
command-list ..., end
Specify a list of commands for breakpoint number
bnum. The commands themselves appear on the
following lines. Type a line containing just end to
terminate the commands.
To remove all commands from a breakpoint, type
commands and follow it immediately with end; that
is, give no commands.
With no bnum argument, commands refers to the last
breakpoint, watchpoint, or catchpoint set (not to the
breakpoint most recently encountered).
Pressing RET as a means of repeating the last GDB command is disabled within a
command-list.
