Function Syntax

dword SomeIpGetSourcePort ( dword messageHandle );

Description

This function returns the source port (UDP/TCP).

Parameters

messageHandle: Handle of the received SOME/IP message. Note: This function can only be called within the OnSomeIpMessage callback function.

void OnSomeIpMessage( DWORD messageHandle )
{
  DWORD srcPort       = 0;
  LONG  errorCode     = 0;
  LONG  errorOccured  = 0;

  // get data from SOME/IP message
  if((srcPort = SomeIpGetSourcePort(messageHandle)) == 0)
  {
    // check if last function was executed correct
    if((errorCode = SomeIpGetLastError()) != 0)
    {
      write("SOME/IP IL error occured: Error code: %d", errorCode);
      errorOccured = 1;
    } // if
  } // if

  if(errorOccured == 0)
  {
    write("SOME/IP message from Source Port %d received",srcPort);
  } // if
}
