NAME

6       explain_write_or_die - write to a file descriptor and report errors
7

SYNOPSIS

9       #include <libexplain/write.h>
10       void   explain_write_or_die(int   fildes,   const   void   *data,  long
11       data_size);
12

DESCRIPTION

14       The explain_write_or_die function is used to call the  write(2)  system
15       call.   On  failure  an explanation will be printed to stderr, obtained
16       from explain_write(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              ssize_t result = explain_write_or_die(fildes, data, data_size);
22
23       fildes  The fildes, exactly as to be  passed  to  the  write(2)  system
24               call.
25
26       data    The data, exactly as to be passed to the write(2) system call.
27
28       data_size
29               The  data_size,  exactly as to be passed to the write(2) system
30               call.
31
32       Returns:
33               This function only returns on success.  On failure,  prints  an
34               explanation and exits.
