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.

	       explain getpeername(2) errors

       exit(2) terminate the calling process

NAME

       explain_accept4_or_die - accept a connection on a socket and report errors

SYNOPSIS

       #include <libexplain/accept4.h>
       int explain_accept4_or_die(int fildes, struct sockaddr *sock_addr, socklen_t *sock_addr_size, int flags);
       int explain_accept4_on_error(int fildes, struct sockaddr *sock_addr, socklen_t *sock_addr_size, int flags);

DESCRIPTION

       The  explain_accept4_or_die  function  is  used	to  call  the accept4(2) system call. On failure an explanation will be printed to stderr,
       obtained from the explain_accept4(3) function, and then the process terminates by calling exit(EXIT_FAILURE).

       The explain_accept4_on_error function is used to call the accept4(2) system call. On failure an explanation  will  be  printed  to  stderr,
       obtained from the explain_accept4(3) function, but still returns to the caller.

       fildes  The fildes, exactly as to be passed to the accept4(2) system call.

       sock_addr
	       The sock_addr, exactly as to be passed to the accept4(2) system call.

       sock_addr_size
	       The sock_addr_size, exactly as to be passed to the accept4(2) system call.

       flags   The flags, exactly as to be passed to the accept4(2) system call.

RETURN VALUE

       The  explain_accept4_or_die  function  only  returns on success, see accept4(2) for more information. On failure, prints an explanation and
       exits, it does not return.

       The explain_accept4_on_error function always returns the value return by the wrapped accept4(2) system call.

EXAMPLE

       The explain_accept4_or_die function is intended to be used in a fashion similar to the following example:
	      int result = explain_accept4_or_die(fildes, sock_addr, sock_addr_size, flags);

SEE ALSO

       accept4(2)
	       accept a connection on a socket

       explain_accept4(3)
	       explain accept4(2) errors

       exit(2) terminate the calling process
