n
Number of bytes actually written. Might be smaller than ul_ByteCount.
Return Value
Returns FDX_OK on success or a negative error code on error.
Error Codes: FDX_ERR
Return Value:
ul_BytesWritten
Description:
FDX_OK
ul_ByteCount
Frame is sent to BIU.
Note:
Even if ul_ByteCount of the frame exceeds VL associated
MaxFrameLength which was defined with FdxCmdTxCreateVL the
frame is sent to BIU if the data buffer
(*)
size is big enough.
FDX_OK 0
Data
buffer
(*)
in BIU was full, not able to take this frame
FDX_ERR
0
Vl is not initialized, or does not exist
FDX_ERR
0
SubVl not initialized
(*)
Data buffer size is defined with function
FdxCmdTxCreateVL
, parameter
ul_FrameBufferSize.
