is_relative_filename - Man Page

#include <allegro.h>

int is_relative_filename(const char *filename);

Returns TRUE if the filename is relative or FALSE if it is absolute. Note that an absolute filename under DOS (with a device separator) will be considered as relative under Unix, because there absolute paths always start with a slash.
