explain_setsockopt_or_die - get and set options on sockets and report errors
#include <libexplain/setsockopt.h>
void explain_setsockopt_or_die(int fildes, int level, int name, void *data,
socklen_t data_size);
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.
- setsockopt(2)
- get and set options on sockets
- explain_setsockopt(3)
- explain setsockopt(2) errors
- exit(2)
- terminate the calling process
