`pdfDeleteEmbeddedFile`

Remove an attachment so it is not written to the output.

Purpose — Remove an attachment so it is not written to the output.

Description — Tombstones the slot (name and data cleared; the slot is skipped when /EmbeddedFiles is serialized). Handles of other attachments do not shift, and pdfGetEmbeddedFileCount still counts the deleted slot; reads on a deleted handle return FALSE. Deleting the same handle twice fails.

BOOL32 __stdcall pdfDeleteEmbeddedFile(PPDF IPDF, uint32_t Handle);

Return value — TRUE if the handle referenced a live attachment.
