FPDFAnnot_GetFormAdditionalActionJavaScript method

int FPDFAnnot_GetFormAdditionalActionJavaScript(FPDF_FORMHANDLE hHandle, FPDF_ANNOTATION annot, int event, Pointer<FPDF_WCHAR> buffer, int buflen,)

Experimental API. Get the JavaScript of an event of the annotation's additional actions. |buffer| is only modified if |buflen| is large enough to hold the whole JavaScript string. If |buflen| is smaller, the total size of the JavaScript is still returned, but nothing is copied. If there is no JavaScript for |event| in |annot|, an empty string is written to |buf| and 2 is returned, denoting the size of the null terminator in the buffer. On other errors, nothing is written to |buffer| and 0 is returned.

hHandle - handle to the form fill module, returned by FPDFDOC_InitFormFillEnvironment(). annot - handle to an interactive form annotation. event - event type, one of the FPDF_ANNOT_AACTION_* values. buffer - buffer for holding the value string, encoded in UTF-16LE. buflen - length of the buffer in bytes.

Returns the length of the string value in bytes, including the 2-byte null terminator.
