Macro Definition Documentation

RECV

#define RECV	(		buf,
			sz
	)

Value:

recvd = netplay_recv(&connection->recv_packet_buffer, connection->fd, (buf), (sz), false); \
 if (recvd >= 0 && recvd < (ssize_t) (sz)) \
 { \
 netplay_recv_reset(&connection->recv_packet_buffer); \
 return true; \
 } \
 else if (recvd < 0)
