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);
