NAME¶explain_write_or_die - write to a file descriptor and report errors
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);
- The fildes, exactly as to be passed to the write(2) system call.
- The data, exactly as to be passed to the write(2) system call.
- The data_size, exactly as to be passed to the write(2) system call.
- This function only returns on success. On failure, prints an explanation and exits.
