make_relative_filename(3alleg4) 				  Allegro manual				   make_relative_filename(3alleg4)

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

get_filename - Returns a pointer to the filename portion of a path. Allegro game programming library. SYNOPSIS
#include <allegro.h> char *get_filename(const char *path); DESCRIPTION
Finds out the filename portion of a completely specified file path. Both `' and `/' are recognized as directory separators under DOS and Windows. However, only `/' is recognized as directory separator under other platforms. Example: get_executable_name(name, sizeof(name)); allegro_message("Running `%s' ", get_filename(name)); Note that Allegro won't perform any IO operations during the verification. This means that if you have `/a/path/like/this/', which doesn't have a filename, the function will return a pointer to the trailing null character. However, if you have `/a/path/like/this', Allegro will return a pointer to `this', even if it is a valid directory. RETURN VALUE
Returns a pointer to the portion of `path' where the filename starts, or the beginning of `path' if no valid filename is found (eg. you are processing a path with backslashes under Unix). SEE ALSO
