The OpenMP implementation must define several entry point symbols through which execution must pass when particular events occur and data collection for OMPD is enabled. A tool can enable notification of an event by setting a breakpoint at the address of the entry point symbol.
Entry point symbols have external C linkage and do not require demangling or other transformations to look up their names to obtain the address in the OpenMP program. While each entry point symbol conceptually has a function type signature, it may not be a function. It may be a labeled location
