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.
