SYNOPSIS
       #include <libexplain/read.h>
       long explain_read_or_die(int fildes, const void *data, long data_size);

DESCRIPTION
       The  explain_read_or_die  function  is used to call the read(2) system call.  On failure an explanation will be printed to stderr, obtained
       from explain_read(3), and then the process terminates by calling exit(EXIT_FAILURE).

	      explain_read_or_die(fildes, data, data_size);

       fildes  The fildes, exactly as to be passed to the read(2) system call.
