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.
