[gs-devel] Problems with stdin and return code -110

[Sheri Steeves]

Russell,

My stdin is called a number of times, as expected. The file handle is
opened in my code and passed to the function through the caller_handle
parameter, where I retrieve the open handle. I had removed some of the
error checking and other code for brevity.

I did get around my wide name problem by copying the file to a temporary
location, and handling PDF, PS and EPS this way - giving me only a
single path of code to maintain, as I was under the impression that you
could only stream EPS and PS.

>From the online docs:
http://pages.cs.wisc.edu/~ghost/doc/svn/Use.htm#Pipes
Ghostscript cannot read PDF files from standard input or a pipe because
the PDF language inherently requires random access to the file. Thus '-'
only works with PostScript documents.

This may be where my confusion started.

If you are saying that I can stream the PDF in through the stdin, and
that ghostscript makes it's own temp copy for random access, I may go
back to the stdin approach to avoid the extra temp file copy.
 
Best Regards,
Sheri
