NAME

       explain_fwrite_or_die - binary stream output and report errors

SYNOPSIS

       #include <libexplain/fwrite.h>
       size_t explain_fwrite_or_die(const void *ptr, size_t size, size_t nmemb, FILE *fp);

DESCRIPTION

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

       This function is intended to be used in a fashion similar to the following example:
              size_t result = explain_fwrite_or_die(ptr, size, nmemb, fp);

       ptr     The ptr, exactly as to be passed to the fwrite(3) system call.

       size    The size, exactly as to be passed to the fwrite(3) system call.

       nmemb   The nmemb, exactly as to be passed to the fwrite(3) system call.

       fp      The fp, exactly as to be passed to the fwrite(3) system call.

       Returns:
               This  function  only  returns  on  success.  On failure, prints an explanation and
               exits.
