HSK Device Driver Interface for VxWorks* 5.4
pPackett
Pointer to a data packet being sent to the specified device driver. It is the responsibility of the device driver to validate the packet contents. Upon returning from this callback, the RH driver deallocates the data packet. The data packet must be smaller than 1KB. The RH driver places no restrictions on the type of data used for two reasons:
•The RH driver has no direct knowledge of the structure of this information
•The RH driver is not required to perform any actions with this object
iLen
Length in bytes of the data packet being sent.
pci
A PCI location structure. This structure contains the PCI bus, device, and function location of the device that is to receive the message packet.
Return Value
HSI_STATUS_SUCCESS if successful; otherwise HSI_STATUS_FAILURE
