function call

The way I do it is to use a wrapper function call with a macro.

#define doit(a) wrapper( (a), __FILE__, __LINE__ )

doit( int arg ) { // do something }

wrapper_doit( int arg, char *where1, int where2 ) { printf( "%s %d\n", where1, where2 ); doit( arg ); }

All calls to doit will be rerouted to wrapper_doit and will printout the file and line number where the call is.

You can use the gcc function "void * __builtin_return_address (unsigned int level)" function. The with level 0 it returns the address where the function that used __builtin_return_address returns to. For e.g., f1() called f2() and f3() and f3() called __builtin_return_address then with level 0 it returns the address of the next instruction in f2() after f3() call.
