client = SOCKACCEPT(server)

Removes and returns the next established connection from the listening socket’s pending queue. Returns a non-negative file descriptor on success, or -1 if no connection is ready (or on error).

Note: SOCKACCEPT is non-blocking: it returns immediately. If there are no connections to accept, it will return -1.

How to use it

server is the file descriptor returned by SOCKLISTEN(ip$, port, backlog).
Call repeatedly in your main loop to accept clients as they become ready.
Use the returned client descriptor with SOCKWRITE, SOCKREAD, INSOCKET$, and SOCKCLOSE.
The pending queue is FIFO; only the head is checked each call.

Examples

REM Minimal accept loop
server = SOCKLISTEN(NETINFO$("ip"), 2000, 5)
IF server < 0 THEN PRINT "Listen failed": END
PRINT "Listening on port 2000"
 
REPEAT
    client = SOCKACCEPT(server)
    IF client >= 0 THEN
        SOCKWRITE client, "HELLO!" + CHR$(13) + CHR$(10)
        SOCKCLOSE client
    END IF
UNTIL INKEY$ <> ""
 
SOCKCLOSE server

Notes

Returns -1 when no established connection is available; try again later.
Each successful call returns a new client descriptor; the server remains listening.
