al_remove_filename — Allegro 5 API
#include <allegro5/allegro.h> bool al_remove_filename(const char *path)
Delete the given path from the filesystem, which may be a file or an empty directory. This is the same as al_remove_fs_entry(3), except it expects the path as a string.
Returns true on success, and false on failure. Allegro's errno is filled in to indicate the error.
