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

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:
