Provides links to constructs used in the OpenMP API.
The Visual C++ implementation of the OpenMP standard includes the following constructs.
| Construct | Description |
|---|---|
| Directives | Provides links to directives used in the OpenMP API. |
| Clauses | Provides links to clauses used in the OpenMP API. |
| Functions | Provides links to functions used in the OpenMP API. |

The Visual C++ OpenMP run-time library functions are contained in the following libraries.
| OpenMP run-time library | Characteristics |
|---|---|
| VCOMP.LIB | Multithreaded, dynamic link (import library for VCOMP140.DLL). |
| VCOMPD.LIB | Multithreaded, dynamic link (import library for VCOMP140D.DLL) (debug) |
If _DEBUG is defined in a compilation and if #include <omp.h> is in source code, VCOMPD.LIB will be the default lib, otherwise, VCOMP.LIB will be used.
You can use /NODEFAULTLIB (ignore libraries) to remove the default lib and explicitly link with the lib of your choice.
The OpenMP DLLs are in the Visual C++ redistributable directory and need to be distributed with applications that use OpenMP.
