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);
