append_filename: Concatenates a filename to a path. Allegro game programming library.
NAMEappend_filename - Concatenates a filename to a path. Allegro game programming library.
DESCRIPTIONConcatenates the specified filename onto the end of the specified path, storing at most `size' bytes into the `dest' buffer. If `path' doesn't have a trailing path separator, the function will append one 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:
append_filename(buf, "/home/user", "prog.bin", sizeof(buf));
RETURN VALUEReturns a copy of the `dest' parameter.
