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.
