Description
- Protocol-specific escape mechanism for sending a message to a call.
Prototype
- DWORD nccSendCallMessage ( NCC_CALLHD callhd,
void *message,
unsigned *size )
- callhd Call handle to which message should be sent.
- message Pointer to buffer containing protocol-specific call message.
- size Size of message buffer.
Return Values
Events
- A protocol-specific event may be returned depending upon the protocol implementation.
Details
- This function sends a protocol-specific call message to a protocol. The protocol defines the allowed protocol-specific call messages that it can receive. Use of this function requires that the application be aware of which protocol is being used.
- You cannot send a call message that causes a state change as a result of successful message delivery.
- Some protocols do not support the capability to send a call message. The application can determine if the protocol supports this capability by examining the NCC_CAP_SEND_CALL_MESSAGE bit in the capabilitymask returned by nccQueryCapability.
- Refer to your protocol-specific documentation for more details on the use of this function.
