Getting the last modified date of a file in C

Question

I want to get the last modified date of a file in C. Almost all sources I found use something along this snippet:

char *get_last_modified(char *file) {
    s

On OS X, st_mtimespec.tv_sec is the equivalent of st_mtime.

To make this portable, do

#ifdef __APPLE__
#ifndef st_mtime
#define st_mtime st_mtimespec.tv_sec
#endif
#endif

and then use st_mtime.
