| lpfnAuthProc | LPFNIG_PDF_AUTHPROC | Authorization callback, called only if the file has been secured (that is, if the file has either the user or the master password set). This callback should obtain whatever information is needed to determine whether the user is authorized to open the file, then call IG_PDF_doc_perm_request (which returns the permissions that the authentication data enables). |
| lpAuthData | LPVOID | Pointer to user-supplied data to pass to lpfnAuthProc each time it is called. |
