The statistics API is made available to user applications by two C-language header files and a dynamic link library (DLL).
Two platform-independent C-language header files are provided for developing user applications.
ctgstats.h defines the API function calls and datatypes required to use the API functions.
ctgstdat.h defines the set of query return codes that might be seen by a statistical user application. The set of query return codes can vary according to the statistics protocol version provided by the CICS® Transaction Gateway daemon.
The statistics API runtime DLL is provided for each of the supported CICS Transaction Gateway hardware platforms. It is supplied as a platform-specific DLL binary. It must be available during the runtime of the statistical user application.
