[gs-devel] problem using -sOutputFile=%stdout

[Adam Heinz]

Sorry if this is a duplicate.  My network was being a bit bizarre last week and I don't see this message in the archives.

> I'm currently working on getting our rasterization moved off disk; hopefully entirely into buffers.  I've been succesful using "-" as my input file, then reading in our buffer during calls to my gsdll_stdin() callback set via gsapi_set_stdio().  Now that I'm working on writing to a buffer, I've tried (on Windows, using gsapi_init_with_args()):
> 	-sOutputFile=%%stdout
> 	-sOutputFile=%%pipe%%
> 	-sOutputFile=-
