Recv

• #include <sys/types.h>

• #include <sys/socket.h>

• int recv(int s, void *buf, size_t len, int flags);

• Receives a message from a socket, normally used on a connection mode socket

• Returns as much available information as the size of the buffer supplied can hold.

• If the socket is connection-oriented and the remote side has shut down the connection gracefully, a recv call completes with 0 bytes received. If the connection has been reset, recv fails and sets errno to ECONNRESET.
