A compliant implementation must supply a set of definitions for the OMPD runtime entry points, OMPD third-party tool callback signatures, third-party tool interface functions and the special data types of their parameters and return values. These definitions, which are listed throughout this chapter, and their associated declarations shall be provided in a header file named omp-tools.h. In addition, the set of definitions may specify other implementation-specific values.

The ompd_dll_locations variable, all OMPD third-party tool interface functions, and all OMPD runtime entry points are external symbols with C linkage.
