| Members | Description |
|---|---|
| uint8_t* pData; | input: data buffer to be sent as part of the request, callback : pointer to the received data buffer |
| uint16_t dataSize; | input: number of bytes in the input data buffer, callback: number of bytes in the received data buffer |
| uint16_t seqNumber; | monotonic number matching requests and replies |
| PPP_ECHO_CALLBACK callback; | callback function to be called when a reply is received or an error occurred |
| const void* param; | parameter to be used in the callback; it is user defined, PPP does not use it in any way |
Description
This structure defines the information required for sending an PPP request that contains user data.
Remarks
When the callback is made with an error result, the PPP_ECHO_REQUEST structure may identify the request, if no reply was received (for example timeout)
This is a PPP ECHO requestBeing a network interface a regular ICMP ping could be used instead
