A socket handle (usually returned by either SOCKET_ACCEPT or SOCKET_CONNECT).
Reads data from a socket connection.
A socket handle (usually returned by either SOCKET_ACCEPT or SOCKET_CONNECT).
A pre-allocated byte array to read into.
The number of bytes read from the socket.
Before calling SOCKET_READ, you must initialize data to be a byte array of sufficient size to hold the data sent from the client. It is up to the programmer to convert the data in the byte array into whatever form the server or client expects to process. PV-WAVE provides several routines for converting data from one type to another, including BYTE, BYTEORDER, COMPLEX, DOUBLE, FLOAT, LONG, and STRING.
PRO CLIENT
host = 'localhost'
port = 1500
socket = SOCKET_CONNECT(host,port)
IF socket EQ -1 OR socket EQ -2 THEN BEGIN
PRINT, 'SOCKET_CONNECT failed with return code: ', socket
RETURN
ENDIF
data = BYTARR(15)
nbytes = SOCKET_READ(socket,data)
PRINT, 'CLIENT received: ', STRING(data)
SOCKET_CLOSE, socket
END
