NAME
an_send - send incoming data to a proxy-capable socket
SYNOPSIS
#include <antinat.h>
int an_send(ANCONN s, void * buf, int length, int flags);
DESCRIPTION
The an_send(3) function is used to send incoming data to a proxy-capable socket. The socket must be in the accepted or connected state. If the socket is in blocking mode, the an_send(3) function will block until some data is successfully sent into the socket. In non-blocking mode, if no data can be sent, the return value will be -1, and errno set to EAGAIN. To fetch data back from the recipient of this data, use an_recv(3).
s is a socket previously created with an_new_connection(3), and accepted or connected with an_accept(3), an_connect_tohostname(3) or an_connect_tosockaddr(3).
buf is a buffer containing the data to send.
length is the number of bytes to send from the user supplied buffer.
flags are flags, reserved for future use. Currently, there are no flags guaranteed to be supported across versions of this library. This parameter must be zero.
RETURN VALUE
The return value is the number of bytes sent from buf, or -1 if an error occurs.
ERRORS
If an error occurs, the return value will be -1. errno will be set to provide more information about the cause of the error.
