NAME
explain_getsockopt_or_die - get and set options on sockets and report
errors
SYNOPSIS
#include <libexplain/getsockopt.h>
void explain_getsockopt_or_die(int fildes, int level, int name, void
*data, socklen_t *data_size);
DESCRIPTION
The explain_getsockopt_or_die function is used to call the
getsockopt(2) system call. On failure an explanation will be printed
to stderr, obtained from explain_getsockopt(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_getsockopt_or_die(fildes, level, name, data, data_size);
fildes The fildes, exactly as to be passed to the getsockopt(2) system
call.
level The level, exactly as to be passed to the getsockopt(2) system
call.
name The name, exactly as to be passed to the getsockopt(2) system
call.
data The data, exactly as to be passed to the getsockopt(2) system
call.
data_size
The data_size, exactly as to be passed to the getsockopt(2)
system call.
Returns:
This function only returns on success. On failure, prints an
explanation and exits.
