Hi,

I have been having a lot of fun  experimenting with websockets
(really... it is a neat technology) but belive there may be an error
in the documentation regarding the SocketRecv() function.

The documentation shows the format to be...

SocketRecv( <nSocket>  , ;
            @<cBuffer> , ;
            [<nLength>], ;
            [<nFlag>]  , ;
            [@<nError>]  ) --> nBytesRead

I belive the nFlag parameter is misplaced as I encountered problems
when using this function.

Frurther investigation shows the Alaska samples (line 208 in
server.prg)  appers to confirm my suspicions...

nBytes := SocketRecv( ::nSocket, @cLength, 4, @nError )

Where nFlag does not have a presence defined appears to confirm this.

I would thinks that the function is expecting...

SocketRecv( <nSocket>  , ;
            @<cBuffer> , ;
            [<nLength>], ;
            [@<nError>]  ) --> nBytesRead

But of course I could only speculate where< nFlag> fits in.

Regards... Jonathan

Hi Jonathan,

The documentation is correct regarding the parameter profile. Checking the 
samples I realize that infact the code is not according documentation. I 
took a note to have it corrected in a future update.

The reason why the sample is working is because the variable nError is 
assigned the numeric value 0 which is a valid flag.

With my best regards,
