C2xIsTokenAvailable

Valid for: CANoe DE

​
Function Syntax

long C2xIsTokenAvailable( long packet, char protocolDesignator[], char tokenDesignator[] );

​
Description

This function checks if the specified token is part of the packet. Note: For ASN.1 based protocols, tokens that are not set are not part of the packet between the functions calls of C2xInitPacket and C2xCompletePacket. For other protocols, the non-optional tokens are always part of the packet.

​
Parameters

  • packet: Handle of a packet that has been created with C2xInitPacket.
  • protocolDesignator: Name of the protocol.
  • tokenDesignator: Name of the token.

​
Return Values

  • 1: Token is part of the packet.
  • 0: Token is not part of the packet.

​
Example

long packet;

//create geoNetworking unicast
packet = C2xInitPacket("geoNetworking");

//spvNetAddr is optional but headertype (ht) is unicast per default which contains spvNetAddr
if (!C2xIsTokenAvailable(packet, "geoNetworking","spvNetAddr"))
{
  write("error! spvNetAddr is not available in geoNetworking unicast");
}

//transform packet to geoNetworking broadcast
if (C2xSetTokenInt(packet, "geo_cnh", "ht", 4) != 0)
{
  write("error! C2xSetTokenInt failed");
}
if (C2xResizeToken(packet, "geoNetworking", "header", 384) != 0)
{
  write("error! C2xResizeToken failed");
}

//broadcast does not contain spvNetAddr
if (C2xIsTokenAvailable(packet, "geoNetworking", "spvNetAddr"))
{
  write("error! spvNetAddr is available in geoNetworking broadcast");
}
