canonicalize_filename - Converts any filename into its canonical form. Allegro game programming library.
#include <allegro.h> char *canonicalize_filename(char *dest, const char *filename, int size);
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; ... 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").
Returns a copy of the `dest' parameter.
