explain_read_or_die(3)	   Library Functions Manual	explain_read_or_die(3)

NAME
       explain_read_or_die - read from a file descriptor and report errors

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).

       This function is	intended to be used in a fashion similar to  the  fol-
       lowing example:
	      explain_read_or_die(fildes, data,	data_size);

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

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

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

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