NAME

explain_write_or_die - write to a file descriptor and report errors  

SYNOPSIS

#include <libexplain/write.h>

void explain_write_or_die(int fildes, const void *data, long data_size);  

DESCRIPTION

The explain_write_or_die function is used to call the write(2) system call. On failure an explanation will be printed to stderr, obtained from explain_write(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:

ssize_t result = explain_write_or_die(fildes, data, data_size);
fildes
The fildes, exactly as to be passed to the write(2) system call.
data
The data, exactly as to be passed to the write(2) system call.
data_size
The data_size, exactly as to be passed to the write(2) system call.
Returns:
This function only returns on success. On failure, prints an explanation and exits.
