Description

The SOCKET_READ() function is used to read data from an open socket connection. The <expN> is the socket number returned from SOCKET_OPEN() or SOCKET_SERVER().

Example

// read the JSON encoded object from the socket
data = socket_read(skt)
 
// assume we are connected to node.js (as an example) 
// and decode the JSON string
myobj = json_decode(data)
 
// now myobj is a VFP object with all the properties 
// (and subobjects/arrays etc)
