void* callstack[128];

int frames = backtrace(callstack, 128);

for(int i=0;i<frames;++i)

{

Dl_info info;

int res = dladdr(callstack[i], &info);

if(res!=0)

{

size_t length=0;

int status=0;

char* name = __cxxabiv1::__cxa_demangle(info.dli_sname,NULL,&length,&status);

printf (" : %s + %d %s\n", (0 == status) ? name : info.dli_sname, (unsigned int)((unsigned int)callstack[i] - (unsigned int)info.dli_saddr), info.dli_fname);

}

I get the name of the function and its arguments but I would like to have the source file's name and the line number of each address of the stack. I know that gdb can do this with "info line *addr", but I want to do it programmatically.

Is there a way to get the source name/line number from backtrace or is it possible to call gdb commands programmatically?

Thanks for any help,

Sam
