Detailed Description

This is how the user does cctalk communications.

This structure is passed around inside the cctalk module. The user will fill out the structure with the Tx packet length. The maximum time this transaction is expected to take in mS. The biggest expected Rx packet size returned. Then send this cctalk operation to the cctalk module for it to be queued to be sent over the cctalk communications bus.

Field Documentation

unsigned char sCCTALK_OPERATION::abRxPacket[ eCCT_MAX_PACKET_SIZE ]

Location to store the data received from the cctalk device

unsigned char sCCTALK_OPERATION::abTxPacket[ eCCT_MAX_PACKET_SIZE ]

Packet to transmit on the tty

teCCTALK_CHANNEL sCCTALK_OPERATION::eCctalkChannel

The channel this packet is destined for

unsigned long sCCTALK_OPERATION::lMaxReplySize

The maximum size of the expected reply packet size must be less that eCCT_MAX_PACKET_SIZE will be silently truncated

unsigned long sCCTALK_OPERATION::lRxPacketSize

The number of actual received bytes

unsigned long sCCTALK_OPERATION::lTimeout

Maximum time to wait in mS for a reply from the bus

unsigned long sCCTALK_OPERATION::lTxPacketSize

The number of bytes in the Tx packet buffer to send

struct sCCTALK_OPERATION* sCCTALK_OPERATION::psNext

Pointer to the next operation in the list

int sCCTALK_OPERATION::zlCctalkSockHdl

The socket handle to send the reply packet back on
