        !            15: .SH DESCRIPTION
        !            16: \fIMktemp\fP creates a unique file name and returns the address of
        !            17: the template.  The template should contain a file name with trailing
        !            18: \fIX\fP's, normally something like \fI/tmp/tempXXXXXX\fP.  The \fIX\fP's
        !            19: are replaced by the current process number and/or a unique letter
        !            20: combination.  \fIMkstemp\fP makes the same replacement to the template
        !            21: but opens the template file and returns a file descriptor open for
        !            22: reading and writing.  \fIMkstemp\fP avoids the race between testing
        !            23: whether the file exists and opening it for use.  The number of file
        !            24: name combinations \fImktemp\fP and \fImkstemp\fP will try depends on
        !            25: the number of \fIX\fP's placed on the end of the template; six \fIX\fP's
        !            26: will result in them trying roughly 26 ** 6 combinations.
        !            27: .SH "SEE ALSO"
        !            28: access(2), getpid(2), open(2)
        !            29: .SH DIAGNOSTICS
        !            30: \fIMktemp\fP returns NULL on failure, \fImkstemp\fP returns -1 if no
        !            31: suitable file could be created.
