NAME

       explain_asprintf_or_die - print to allocated string and report errors

SYNOPSIS

       #include <libexplain/asprintf.h>
       int explain_asprintf_or_die(, ...);
       int explain_asprintf_on_error(, ...);

DESCRIPTION

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

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

RETURN VALUE

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

       The explain_asprintf_on_error function always returns the  value  return  by  the  wrapped
       asprintf(3) system call.

EXAMPLE

       The  explain_asprintf_or_die  function  is intended to be used in a fashion similar to the
       following example:
              int result = explain_asprintf_or_die();
