NAME

     tmpnam - create a name for a temporary file

SYNOPSIS

     #include <stdio.h>

     char *tmpnam(char *s);

DESCRIPTION

     The tmpnam() function generates a unique temporary  filename
     using  the path prefix P_tmpdir defined in <stdio.h>. If the
     argument s is NULL,  tmpnam()  returns  the  address  of  an
     internal  static  area  which  holds  the filename, which is
     overwritten by subsequent calls to tmpnam().  If  s  is  not
     NULL, the filename is returned in s.

RETURN VALUE

     The tmpnam() function returns a pointer to the  unique  tem-
     porary  filename,  or  NULL  if a unique name cannot be gen-
     erated.

ERRORS

     EEXIST
          Unable to generate a unique filename.
