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