SOCKET net_send(SOCKET socket, const char * buffer, int size, int Seconds);

Parameters

socket

Socket returned by net_socket, socket, net_accept, or accept.

buffer

Pointer to the data to ne sent.

size

Number of bytes to send.

Seconds

Timeout in seconds. This parameter is ignored if zero, which means the operation waits indefinitely for sockets in blocking mode or returns immediately for sockets in non-blocking mode. Value RTIP_INF will wait indefinitely.

return value

The number of bytes queued for sending or SOCKET_ERROR. If an error occurred, call xn_getlasterror and xn_geterror_string to return the error value. Section Error Codes further describes each error.

For secure sockets, the data to be sent is encrypted. Then, function send is called internally.
