NAME
       mktemp - make a unique file name

SYNOPSIS
       #include <stdlib.h>

       char *mktemp(char *template);

DESCRIPTION
       mktemp replaces the contents of the string pointed to by template
       with a unique file name, and returns template.  The string in
       template should look like a file name with six trailing Xs; mktemp
       will replace the Xs with a character string that can be used to
       create a unique file name.

DIAGNOSTIC
       mktemp will assign to template the empty string if it cannot create a
       unique name.

NOTES
       mktemp can create only 26 unique file names per process for each
       unique template.
