Hi Scott,
f) if len > 0, go back to step (d). Keep doing this until len <= 0, that's when you've reached >the end of the data on the pipe.
I did a quick test.The Api should return a document of 21.931 bytes (but it does not return the size and can't know this in advance) then I try to read one block of data at the time as you suggest in d) and f).
midrange.com
------
p_buffer = %alloc(8196);
DoU len <= 0;
len = read(output(1): p_buffer: 8196);
// stream out
If (SDR > 0) and len > 0;
RC = Write(SDR: p_buffer: len);
EndIf;
EndDo;
dealloc p_buffer;
----
The first and second read return len=8196; the 3rd returns
5539 (8196+8196+5539=21931) but It seems that when I reach
the end of data the program does not return len = 0 but it
hangs on the 4th read instruction.
And if the document is not found the read hangs at first run.
Any suggestion ?
