NAME

6       explain_fwrite_or_die - binary stream output and report errors
7

SYNOPSIS

9       #include <libexplain/fwrite.h>
10       size_t  explain_fwrite_or_die(const  void  *ptr,  size_t  size,  size_t
11       nmemb, FILE *fp);
12

DESCRIPTION

14       The explain_fwrite_or_die function is used to call the fwrite(3) system
15       call.   On  failure  an explanation will be printed to stderr, obtained
16       from explain_fwrite(3), and then  the  process  terminates  by  calling
17       exit(EXIT_FAILURE).
18
19       This  function  is intended to be used in a fashion similar to the fol‐
20       lowing example:
21              size_t result = explain_fwrite_or_die(ptr, size, nmemb, fp);
22
23       ptr     The ptr, exactly as to be passed to the fwrite(3) system call.
24
25       size    The size, exactly as to be passed to the fwrite(3) system call.
26
27       nmemb   The nmemb, exactly as to be  passed  to  the  fwrite(3)  system
28               call.
29
30       fp      The fp, exactly as to be passed to the fwrite(3) system call.
31
32       Returns:
33               This  function  only returns on success.  On failure, prints an
34               explanation and exits.
