Hey,
So, we now need to decide what goes where.
The list of status code so far is:
- PDF_OK
- PDF_EEOF (read)
- PDF_EAGAIN (read/write)
- PDF_ENOSPC (write)
- PDF_EINVOP (read for write mode and viceversa)
- PDF_ERROR (other error)
- PDF_EBADFILE (invalid data)
- PDF_EIO (future use i/o error)
- PDF_EIMPLLIMIT (filter specific)
- PDF_ENOMEM (filter specific)
- PDF_EINTR (signal interruption)
The backend and the fsys module are deeply related. If we decide we need a
status code in the backend it's very likely that we need it in the fsys mod too.
Then, from the bottom and upwards the returned values would be,
Fsys mod:
- PDF_OK
- PDF_EEOF (read)
- PDF_EAGAIN (read/write)
- PDF_ENOSPC (write)
- PDF_EINVOP (read for write mode and viceversa)
- PDF_EINTR (signal interruption)
- PDF_ERROR (other error)
Stm mod:
- PDF_OK
- PDF_EEOF (read)
- PDF_EAGAIN (read/write)
- PDF_ENOSPC (write)
- PDF_EINVOP (read for write mode and viceversa)
- PDF_EINTR (signal interruption)
- PDF_EBADFILE (invalid data)
- PDF_EIO (future use i/o error)
- PDF_EIMPLLIMIT (filter specific)
- PDF_ENOMEM (filter specific)
- PDF_ERROR (other error)
Additional filter return values:
- PDF_EIMPLLIMIT (filter specific)
- PDF_ENOMEM (filter specific)
- PDF_EBADFILE (invalid data)
Tell me what you think and then i'll proceed.
cheers,
