 Syntax


    cc ... -lc


    char *mktemp (template)
    char *template;


 Description

    The mktemp function replaces the contents of the string pointed to by
    template by a unique filename, and returns the address of template.  The
    string in template should look like a filename with six trailing ``X''s;
    mktemp replaces the ``X''s with a letter and the current process ID.  The
    letter is chosen so that the resulting name does not duplicate an exist-
    ing file.

 Diagnostics

    The mktemp function assigns to template the null string if it cannot cre-
    ate a unique name.
