ARES_SET_SOCKET_CONFIGURE_CALLBACK(3) Introduction to Library Functions

NAME

ares_set_socket_configure_callback - Set a socket configuration
callback

SYNOPSIS

#include <ares.h>

typedef int (*ares_sock_config_callback)(ares_socket_t socket_fd,
int type,
void *userdata)

void ares_set_socket_configure_callback(ares_channel_t *channel,
ares_sock_config_callback callback,
void *userdata)

DESCRIPTION

This function sets a callback in the given ares channel handle.
Cannot be used when ARES_OPT_EVENT_THREAD is passed to
ares_init_options(3).

This callback function will be invoked after the socket has been
created, but before it has been connected to the remote server, which
is an ideal time to configure various socket options. The callback
must return ARES_SUCCESS if things are fine, or return -1 to signal
an error. A returned error will abort the ares operation.
