   Yes, they do. However,
    I ran into an endless loop in skip_whitespace()
   because pdf_stm_read_char() returns c=0 if read_p() is false.
   It should return PDF_EOF instead, shouldn't it?

It has no sense to execute pdf_stm_read_char() in a stream when
read_p() return PDF_FALSE. read_p() indicates if the stream support
reading. Memory streams always support reading while file streams look
at the opening mode for the stream: if it is MODE_READ or MODE_RW then
pdf_read() return PDF_TRUE. It return true if the file stream was
opened in MODE_WRITE. So the return value of read_p() is fixed for
each stream and only depend on the mode specified in
pdf_create_stream().

   It is just a test driver, but --help will help me. 

Thanks.
