canonicalize_filename(3)        Allegro manual        canonicalize_filename(3)



NAME
       canonicalize_filename - Converts any filename into its canonical form.
       Allegro game programming library.

SYNOPSIS
       #include <allegro.h>


       char *canonicalize_filename(char *dest, const char *filename, int
       size);

DESCRIPTION
       Converts any filename into its canonical form, i.e. the minimal
       absolute filename describing the same file and fixing incorrect
       forward/backward slashes for the current platform, storing at most
       `size' bytes into the `dest' buffer. 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:

          char buf[256];
          ...
          canonicalize_filename(buf, "~/../s22/..\\t3st///hi.c",
                                sizeof(buf));
          /* Running this under Unix would
             return: /home/t3st/hi.c */

       Note that this function won't work as expected if the path to
       canonicalize comes from another platform (eg. a "c:\something" path
       will canonicalize into something really wrong under Unix:
       "/current/path/c:/something").

RETURN VALUE
       Returns a copy of the `dest' parameter.
