Gdb trick: the poor man loop
written on Thursday, April 17, 2008
Suppose you are in the middle of a gdb session, and need to print the content of an array or a class implementing operator[]. Here is a simple way to do that which I just discovered:
(gdb) set $pos=0
(gdb) print array[$pos++]
content of array[0](gdb)
content of array[1](gdb)
content of array[2]...
The blank "(gdb)" lines mean i just pressed "return". In this case, gdb executes the previous command again, printing array and incrementing $pos one more time.
Hope this helps, and feel free to comment on any better way to achieve this!
