make_absolute_filename (3) Linux Manual Page
make_absolute_filename – Makes an absolute filename from a path and relative filename. Allegro game programming library.
Synopsis
#include <allegro.h> char *make_absolute_filename(char *dest, const char *path, const char *filename, int size);
Description
Makes an absolute filename from an absolute path and a relative filename, storing at most `size’ bytes into the `dest’ buffer. This is like calling replace_filename() and then canonicalize_filename(). Example:
char buf[256];
…
make_absolute_filename(buf, "/usr/games/",
"../temp.txt", sizeof(buf));
/* This would create /usr/temp.txt */
