See <http://gcc.gnu.org/onlinedocs/gcc/Function-Names.html#index-g_t_0040code_007b_005f_005fPRETTY_005fFUNCTION_005f_005f_007d-identifier-2118>. To use them you'd have to arrange to pass them to your instrumentation routine from a call within the function though, they can't be used to just map a memory address to a function name. To do that will be extremely target-specific and seeing as how gcc supports something like 3 dozen various targets, there's no way to answer that without more details. If you're using a glibc platform, you can use dladdr(); see dlopen(3). But realize this is nonportable, it is a glibc extension. Brian
