I agree with you. Returning a pdf_status_t with an error code could be
better. Like PDF_OK if successful, PDF_ERROR if not, and PDF_EEXIST if
file doesn't exist.
Agreed.
And BTW, we should probably have an additional function for multiple
checks, like a wrapper for the access() function.
Then the pdf_fsys_item_p, pdf_fsys_item_is_readable_p and
pdf_fsys_item_is_writable_p functions could even be macros calling
pdf_fsys_item_access.
That modification would involve to change the filesystem
implementation interface. Not all filesystems will have an access-like
functionality in a native way.
As a matter of convenience we could provide a pdf_fsys_item_access function
that would internally use the pdf_fsys_item_* functions.
