NAME

       explain_tempnam_or_die - create a name for a temporary file and report errors

SYNOPSIS

       #include <libexplain/tempnam.h>
       char *explain_tempnam_or_die(const char *dir, const char *prefix);
       char *explain_tempnam_on_error(const char *dir, const char *prefix);

DESCRIPTION

       The explain_tempnam_or_die function is used to call the tempnam(3) system call. On failure
       an explanation will be printed to stderr, obtained from the  explain_tempnam(3)  function,
       and then the process terminates by calling exit(EXIT_FAILURE).

       The  explain_tempnam_on_error  function  is  used  to  call the tempnam(3) system call. On
       failure an explanation will be printed to stderr,  obtained  from  the  explain_tempnam(3)
       function, but still returns to the caller.

       dir     The dir, exactly as to be passed to the tempnam(3) system call.

       prefix  The prefix, exactly as to be passed to the tempnam(3) system call.

RETURN VALUE

       The  explain_tempnam_or_die  function  only  returns  on  success, see tempnam(3) for more
       information. On failure, prints an explanation and exits, it does not return.

       The explain_tempnam_on_error function always returns  the  value  return  by  the  wrapped
       tempnam(3) system call.

EXAMPLE

       The  explain_tempnam_or_die  function  is  intended to be used in a fashion similar to the
       following example:
              char *result = explain_tempnam_or_die(dir, prefix);
