#include <stdio.h> char *mktemp(char *template); |
template is a file specification that ends with six trailing
X characters. This function replaces the XXXXXX with a
set of characters such that the resulting file name names a nonexisting
file.
Note that since MS-DOS is limited to eight characters for the file name,
and since none of the X's get replaced by a dot, you can only
have two additional characters before the X's.
If a unique name cannot be chosen, NULL is returned. Otherwise
the resulting filename is returned.
