Actually there is one pretty common method to achieve this. Just define a macro
#define bar() debug_bar(__func__)
and then write a small function debug_bar(char *funct_name) which will use this string as you want and will call original bar() function.

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.   Even  I don't have access to the caller function source code.

Thanks for your help.
