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 following 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.
