Re: pgnuplot+wgnuplot does not accept binary from pipe

[Tatsuro M. <tma...@ya...>]

Hi 

I previuosly wrote the mail.
At that time, I think that pgnuplot did not have relation to the matters.
However the pgnuplot have relation to the matter.
This is because the stdin of windows is the windows specific text mode.  
I made a code the following the diff results.

The log results attached as 'temp.dat'

Addition of

_setmode(fileno(stdin), _O_BINARY);

is the most essential change.  Other changes are only for taking the log.

If you have any suggestion to me, please make a reply.

Regards

Tatsuro
