# Development environment

To use the DTM service functions, an application must link to the following files:

- DTM service header file dtmdef.h.

- Import library adidtm.lib (named libadidtm.so under UNIX).

- DTM service Windows dynamic link library adidtm.dll or the UNIX shared library libadidtm.so.

Looking at the annotated source code for the demonstration programs is a good way to start developing your own applications. The demonstration programs are installed in the \nms\ctaccess\demos directory (/opt/nms/ctaccess/demos under UNIX). Each demonstration program has its own subdirectory with the same name as the demonstration program.

Note: The directory structure can vary slightly according to your operating system and installation. Refer to the Natural Access Developer's Reference Manual for specific information about the appropriate text file to examine to retrieve the exact path to the header and library files on your system.
