Question on finding the caller function in C.

[Ravi Sankar <ravisankar.g@xxxxxxxxx>]

Hi,

I would like to know how can I get the function name of the caller in c?.

Like
// c code

void foo(void)
{

bar();
}

void bar(void)
{
  // who is my caller?
}

I don't want to change the caller function code to add arguments etc.

I am doing this for a debugger which shall run on cortex-a8 & Linux. Thanks
for your help.

All i know is that I can know the caller function address using
"__builtin__return_address(0)".
I wonder how can I use this to find out the function name as 'c' string?

Any help is highly appreciated.
