The dsmQueryApiVersionEx function call performs a query request for the API library version that the application client accesses.
All updates to the API are made in an upward-compatible format. Any application client that has an API version or release less than or equal to the API library on the end user's workstation operates without change. See "Summary of Code Changes" in the README.API file for exceptions to upward compatibility. If the dsmQueryApiVersionEx call returns a version or version release that is different from that of the application client, be aware before you proceed that some API calls might be enhanced in a manner that is not supported by the end user's older version of the API.
The application API version number is stored in the dsmapitd.h header file as constants DSM_API_VERSION, DSM_API_RELEASE, DSM_API_LEVEL, and DSM_API_SUBLEVEL.
