Can anybody tell me how to set a breakpoint in gdb on a function that returns a pointer? I know that for foo():
break foo
will take care of it, but what if I have
void *foo()
I tried:
break foo
break *foo
break *(foo)
break (*foo)
None of these worked.
Thanks.
Then use the
break <filename>:<linenumber>
syntax.
Can't. I'm programming this, and the line number changes all the time.
That shouldn't matter unless you have written a script to automate the debugging (or parts of it).Quote:

Considering the fact that both there and here, you've posted claiming that you've been unable to do what is very much allowed in gdb...without any further clarification.... I wouldn't bother the next time.Quote:

I am quite sure that gdb can do this, that's why I am asking. The problem is that I don't know how to do accomplish it. Not trying to start a fight - just trying to get a focused answer to my question. :confused:
Can gdb set a breakpoint on a function. Uh... Yes? If you have a function called foo(), then "break foo" should set a breakpoint there. If it does not, there is something about the situation you are leaving out.
