1537.0. "Buffer Sizes" by SPI0::CKALER () Thu Oct 05 1989 09:35
I am using XDrawSegments and am trying to optimize my output by lumping
as many lines into a single X call as possible. My problem: I define an
array XSegment vectors[MAX_SIZE]. Now, I was using a MAX_SIZE of 5000.
This caused an error from X at run time. I eventually lowered it to 2000
and it works fine. After digging in the X sources, I have found that they
have a buffer size of 8192. Somehow these seem to be releated, I'm sure.
Does anyone know how to increase the buffer sizes? Ideally I would like
to be able to define MAX_SIZE to be like 10000 !

| 1537.1 | Fixed in V2 | STAR::BMATTHEWS | | Thu Oct 05 1989 13:56 | 6 |
| Should work ok with large buffer sizes in DECWindows V2.
There was an XLIB bug in V1 that caused the problem you were seeing.
Also the default buffer size is now 16384 instead of 8192.

Any chance of CHANGING the size? (in V1 or V2)
Hans.
