Re: [Plplot-general] plbuf wr_data: Plot buffer grow failed

[Andrew R. <and...@us...>]

Which driver are you using?

xwin for example has an option "-drvopt unbuffered" which will disable 
buffering. There is no universal user level way of doing this and most
other drivers don't have a similar option.

The variable plbuf_write in the PLStream structure controls whether 
writing to the buffer is allowed. You may be able to set this to 0 in the 
driver you are using to see if this fixes the problem.

Regards

Andrew
