Prototype:
AiReturn FdxCmdTxVLWrite (
AiUInt32 ul_Handle,
const TY_FDX_TX_VL_WRITE_IN *px_TxVLWriteIn,
TY_FDX_TX_VL_WRITE_OUT *px_TxVLWriteOut);
Driver Command:
FDX_TX_VL_WRITE (0x00008060)
Purpose:
This function is used to write data directly to a virtual link buffer. The Virtual link has to be
defined using function
FdxCmdTxCreateVL
or
FdxCmdTxCreateHiResVL
.
