pdfGetInFieldCount

int32_t __stdcall pdfGetInFieldCount(PPDF IPDF);

function pdfGetInFieldCount(const IPDF: PPDF): Integer; stdcall;

Purpose. Return the field count in the currently open import file — the field-cluster counterpart of the several other pdfGetIn* getters (Document Info & Structure Tree/E13) that follow the same convention.

Description. Follows the established pdfGetIn* pattern: fails with the distinct NO_IMPORT_ERR sentinel if no import file is open (not the generic 0).

Return value. The import source's field count; NO_IMPORT_ERR if no import file is open; 0 if IPDF is invalid.
