The C examples are located in C:\Transcend Traffix
Manager\TraffixServer\examples\c and the Visual Basic examples are in C:\Transcend Traffix
Manager\TraffixServer\examples\vb. You should copy one of these samples to your own directory before modifying it.
Attribute lookup programs must be able to find the attripc.dll file when they are running. This file is located in the Traffix Manager install directory. In order that your program can find this file, you should copy your program to the Traffix Manager install directory and run it from there, or you should add the Traffix Manager install directory to the PATH environment variable (it must be added as a system environment variable, not a user variable). Be careful not to overwrite any of the executables already in the Traffix Manager install directory.
Once you have built your attribute lookup program and copied it if necessary, you should add it to the
Library functions available
Table 21 shows a full list of the functions available to attribute lookup programs in the attripc DLL library:

FunctionDescription
GetNextLookup Takes no arguments. Returns an integer. This function waits until Traffix Manager want to determine new attributes for a device, or until Traffix Manager is closing down. If Traffix Manager wants to determine attributes for a device, this returns 1. If Traffix Manager wants your program to exit, this function returns 0.
