Experimental API. Function: FPDF_GetXFAPacketName Get the name of a packet in the XFA array. Parameters: document - Handle to the document. index - Index number of the packet. 0 for the first packet. buffer - Buffer for holding the name of the XFA packet. buflen - Length of |buffer| in bytes. Return value: The length of the packet name in bytes, or 0 on error.

|document| must be valid and |index| must be in the range [0, N), where N is the value returned by FPDF_GetXFAPacketCount(). |buffer| is only modified if it is non-NULL and |buflen| is greater than or equal to the length of the packet name. The packet name includes a terminating NUL character. |buffer| is unmodified on error.
