AfdxGetTokenReal

Valid for: CANoe DE • CANoe:lite DE • CANoe4SW DE • CANoe4SW:lite DE

​
Function Syntax

float AfdxGetTokenReal( long packet, char protocolDesignator[], char tokenDesignator[], long offset, long length );

​
Description

This function returns the specified token’s data as a float value.

​
Parameters

  • packet: Handle of the message that has been created with AfdxInitPacket or from within a callback.
  • protocolDesignator: Name of the protocol, e.g. “udp”.
  • tokenDesignator: Name of the token, e.g. “data”.
  • offset: This is the offset from the beginning of the token’s data area. If this is 0, data is copied starting at byte 0 of the token’s data area.
  • length: The values 4 (32-bit float value) and 8 (64-bit float value) are allowed here. This is the length of the value to be returned from the token’s data area.

​
Return Values

Integer value gathered from the token’s data. With AfdxGetLastError you have to check if the function has been processed successfully.

​
Example

void OnAfdxPacket(long channel, long dir, long flags, long bag, long packet )
{
  double temperature;
  char error[100];

  // get temperature value from payload position 8 as a float (4byte length)
  temperature = AfdxGetTokenReal( packet, "udp", "data", 8, 4 );

  if (AfdxGetLastError() == 0)
  {
    // do something with temperature
  }
  else
  {
    AfdxGetLastErrorText( elCount(error), error );
    write("Error: %s", error );
  }
