NAME
replace_extension - Replaces filename+extension with a new extension tail. Allegro game programming library. SYNOPSIS
#include <allegro.h> char *replace_extension(char *dest, const char *filename, const char *ext, int size); DESCRIPTION
Replaces the specified filename+extension with a new extension tail, storing at most `size' bytes into the `dest' buffer. If the filename doesn't have any extension at all, `ext' will be appended to it, adding a dot character if needed. You can use the same buffer both as input and output because Allegro internally works on a copy of the input before touching `dest'. Example: replace_extension(buf, "C:\game\prog.exe", "dat", sizeof(buf)); RETURN VALUE
Returns a copy of the `dest' parameter. SEE ALSO

NAME
make_relative_filename - Tries to make a relative filename from absolute path and filename. Allegro game programming library. SYNOPSIS
#include <allegro.h> char *make_relative_filename(char *dest, const char *path, const char *filename, int size); DESCRIPTION
Attempts to make a relative filename from an absolute path and an absolute filename, storing at most `size' bytes into the `dest' buffer. This function won't work if the paths are not canonical under the current platform (see canonicalize_filename()). Also, `dest' cannot be used as input value for `path' or `filename'. Example: char base[] = "/long/absolute/path/program.exe"; char user_input[] = "/nice/and/short.txt"; ... make_relative_filename(buf, base, user_input, sizeof(buf)); /* Under Unix buf would contain: ../../../nice/and/short.txt */ RETURN VALUE
Returns a copy of the `dest' parameter if it succeeds or NULL if it fails (eg. under DOS, one path starts with "C:" and another with "A:"). SEE ALSO
