Member Function Documentation

GetStructureSize()

static uint16_t GetStructureSize ( tFR_TAG  nTag, uint8_t  nPayloadLength = 0  )

inlinestatic

Returns the size of this structure.

Parameters

nTag	[in] See tFR_TAG values
nPayloadLength	[in] Payload of frame in words (16-bit) when FR_TAG_FRAME is used, in bytes (8-bit) if FR_TAG_PDU is used!

Returns
