Returns 1, 0 or error.
Description
Whether we have a working document.If an error occurred it is not always clear whether the PDF file was already deleted or if it is still in memory. Therefore, this function can be used to determine whether a PDF file is still in memory.
If an open PDF file is in memory the return value is 1. If no open PDF file is in memory the return value is 0.
See also HaveOpenDocument function in DynaPDF manual.
