explain_accept4_or_die(3)  Library Functions Manual  explain_accept4_or_die(3)

NAME
       explain_accept4_or_die -	accept a connection on a socket	and report er-
       rors

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) sys-
       tem 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,  ob-
       tained  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  ac-
       cept4(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)
