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.

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:").
