RE: FW: Have you seen this?

["Bob Cozzi" <cozzi@xxxxxxxxx>]

One solution, which I implemented in my CGILIB (a CGIDEV2 service program)
is to provide a second cgiGetVarEx() procedure. This one does not have a
return value (other than '1'=Valid, '0'=Bad variable name). Instead, it has
four parms (instead of the two of cgiGetVar and zhbGetVar()). 
It is called like this:

   If     cgiGetVarEx('MYCGIVAR' : %addr(rtnvar) : %size(rtnvar))

Parm1 is the Form field name.
Parm2 is the address of the return variable or dynamically allocated buffer
to receive the return data.
Parm3 is the length of the return variable/buffer.
Parm4 is the occurrence of that variable (which is Parm2 in cgiGetVar and
zhbGetVar).

Then you can pass up to a 16 meg buffer or pointer to the buffer and it
works fine. 
If you're locked into CGIDEV2, which you probably are, you might consider
wrapping the zhbGetVar() proc in your own wrapper and doing something
similar to what I do in cgiGetVarEx().

Steve, your supposition is correct: if ZhbGetVar returned only a 100 byte 
varying value, there would be no problem handling thousands of ZhbGetVar
calls 
in a program.

Of course, I can't change ZhbGetVar because:
   - a lot of user written code would break;
   - many users have requested the ability to return MORE than 32767 bytes. 
Reducing the returned size would only increase the number of requests and 
complaints.
