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.
