Function net_recv

Receives data.

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

Parameters

socket

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

buffer

Buffer to receive the received data.

size

Maximum number of bytes to receive.

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 available in the buffer, 0 if end of file; (TCP only) otherwise 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.

This function calls function recv internally. For secure sockets, the received data is decrypted.
