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.
