mktemp - make a unique filename
SYNOPSIS
char *mktemp (template)
cha r * template;
DESCRIPTION

by * template so that it becomes a unique filename. The string at

characters; mktemp replaces the xs with a letter and the current

a duplicate an existing file.

unique name cannot be created, template will point to a null
(empty) string.
