NAME
     mktemp - make a unique file name

SYNOPSIS
     char *mktemp (template)
     char *template;

HP-UX COMPATIBILITY
     Level:    HP-UX/RUN ONLY

     Origin:   System III

DESCRIPTION
     _M_k_t_e_m_p replaces _t_e_m_p_l_a_t_e by a unique file name, and  returns
     the  address of the template.  The template should look like
     a file or path name with six  trailing  Xs,  which  will  be
     replaced  with  a  letter  and  the current process ID.  The
     letter will be chosen so that the resulting  name  does  not
     duplicate  the  name of an existing file.  If there are less
     than 6 Xs, the letter will be dropped first, and  then  high
     order digits of the process ID will be dropped.

RETURN VALUE
     _M_k_t_e_m_p returns its argument  except  when  it  runs  out  of
     letters, in which case the result is a pointer to the string
     "/".

SEE ALSO
     getpid(2).

BUGS
     It is possible to run out of letters.

     _M_k_t_e_m_p does not check to see if the file name part  of  _t_e_m_-
     _p_l_a_t_e exceeds the system limit of 14 characters.
