Interrupt 0xA0 service 0x40: Install a UDP Cfg Callback
Parameters

Comments
Top of list
Install a UDP Config Server User Callback function.
Must be 0x40.
Pointer to the User Callback function
This API Function installs a User Callback function for the UDP Config Server. If a UDP Cfg Request with the command number 06
arrives, this User Callback function will be called. This allows you to realize your own UDP Config sub protocol and commands.
The UDP Cfg Callback function receives an argument with information about the UDP Cfg Request and its requester. This
information structure and the function must be declared as specified in the description below:
typedef struct UdpCfgSrv_UserCBInfo
{
int length; // Length of this struct
struct sockaddr_in *fromAddrPtr; // Sender address pointer
int udpCfgSD; // UDP Config Server's Socket Descriptor
char *dataPtr; // Data of Request package
unsigned dataLength; // Length of request package
};
void huge MyUdpCfgSrvCB( struct UdpCfgSrv_UserCBInfo *infoPtr );
If the callback function returns with the dataPtr and dataLength fields in the UdpCfgSrv_UserCBInfo structure both non-zero,
the UDP Config Server will send the dataLength bytes from location referenced by dataPtr back to the requester. If the pointer
is set to null or the dataLength field is set to 0, no data will be sent back to the requester.
To remove an installed callback function, call this function with a null pointer.
For more Information on the UDP Config Server and its protocol, refer to the UDP Config Server description available on our website.
Note: The data sent and received is limited to 300 bytes maximum.
