    13  #include <stdio.h>   *        mktemp [OPTION]... [TEMPLATE]
    14  #include <errno.h>   * Create a temporary file or directory, safely, and print its name. If
    15  #include <string.h>   * TEMPLATE is not specified, use tmp.XXXXXXXXXX.

    18     * -q, --quiet
    19     *        suppress diagnostics about file/dir-creation failure
    20     * -u, --dry-run
    21     *        do not create anything; merely print a name (unsafe)
    22     * --tmpdir[=DIR]
    23     *        interpret TEMPLATE relative to DIR. If DIR is not specified,
    24     *        use  $TMPDIR if set, else /tmp.  With this option, TEMPLATE must
    25     *        not be an absolute name. Unlike with -t, TEMPLATE may contain
    26     *        slashes, but even here, mktemp still creates only the final com-
    27     *        ponent.
    28     * -p DIR use DIR as a prefix; implies -t [deprecated]
    29     * -t     interpret TEMPLATE as a single file name component, relative  to
    30     *        a  directory:  $TMPDIR, if set; else the directory specified via
    31     *        -p; else /tmp [deprecated]
