Purpose

Function to open a TCP/IP socket

Syntax

FSOCKOPEN(<expC>, <expN>)

See Also

FCLOSE(), FFLUSH(), FGETS(), FPUTS(), FREAD()

Description

The FSOCKOPEN() function opens a TCP/IP socket. It returns a numeric pointer when the socket is opened successfully, or a -1 if unsuccessful. The <expC> is the hostname of the server, <expN> is the port number. Since the pointer is required to identify an open socket to other functions, always assign the return value to a memory variable.

The FCLOSE() function is used to close a socket which has been opened with FSOCKOPEN().

Example

fp=fsockopen("www.server.com",80)
if fp > 0
    ...
endif
fclose(fp)
