putting breakpoint in a file using "rbreak filename.c:." doesn't work

Question

I want to put breakpoint on all functions of a file. I came across this link : http://sourceware.org/gdb/download/onlinedocs/gdb/Set-Breaks.html#Set-Breaks

It suggest the use of rbreak command for this purpose. When i use "rbreak ." , it works fine as expected and puts breakpoint in all functions of a prog. But when is use

rbreak filename.c:.

This doesn't work at all and no breakpoint is put anywhere. I even tried a variation of this putting spaces around :, but even that doesn't work.

Any idea on how this can be done ? Is it possible at all ? Any help will be greatly appreciated.

thanks, vikas

rbreak filename.cpp:.* works fine for me.

Note that in order to put breakpoint in a file you need to compile the program with debug info, e.g

g++ -g filename.cpp
