pdfDeleteAppEvents

int32_t __stdcall pdfDeleteAppEvents(PPDF IPDF, BOOL32 ApplyEvent, TOCAppEvent Event);

function pdfDeleteAppEvents(const IPDF: PPDF; ApplyEvent: LongBool; Event: TOCAppEvent): Integer; stdcall;

Purpose. Clear a specific application-event bit (Event) from every registered OCG's usage dictionary in the document (the document-wide bulk counterpart of the single-OCG pdfDeleteOCGFromAppEvent, Optional Content (OCG) Layers) — per an inline comment, "clear an application-event bit from every OCG; returns the count modified."

Description. ApplyEvent is accepted by the ABI but never passed through to ClearAppEventH — whatever conditional behavior it implies has no effect; the bit is always cleared from every OCG that has it set, regardless of ApplyEvent's value.

Parameters.

Return value. The number of OCGs actually modified (had the bit set and cleared); 0 if IPDF is invalid or no OCG had that bit set.
