NAME explain_getpeername_or_die - get name of peer socket and report errors
SYNOPSIS #include <libexplain/getpeername.h> void explain_getpeername_or_die(int fildes, struct sockaddr *sock_addr, socklen_t *sock_addr_size);
DESCRIPTION The explain_getpeername_or_die function is used to call the getpeername(2) system call. On failure an explanation will be printed to stderr, obtained from explain_getpeername(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: struct sockadd sock_addr; socklen_t sock_addr_size = sizeof(sock_addr); explain_getpeername_or_die(fildes, &sock_addr, &sock_addr_size); fildes The fildes, exactly as to be passed to the getpeername(2) system call. sock_addr The sock_addr, exactly as to be passed to the getpeername(2) system call. sock_addr_size The sock_addr_size, exactly as to be passed to the getpeername(2) system call. Returns: This function only returns on success, see getpeername(2) for more information. On failure, prints an explanation and exits.
