Intel® oneAPI Math Kernel Library Developer Reference - C
Terminates Intel® oneAPI Math Kernel Library execution environment and frees resources allocated by the library.
void mkl_finalize(void);
This function frees resources allocated by Intel® oneAPI Math Kernel Library. Once this function is called, the application can no longer call Intel® oneAPI Math Kernel Library functions other thanmkl_finalize.
In particular, the mkl_finalizefunction enables you to free resources when a third-party shared library is statically linked to Intel® oneAPI Math Kernel Library. To avoid resource leaks that may happen when a shared library is loaded and unloaded multiple times, callmkl_finalize each time the library is unloaded. The recommended method to do this depends on the operating system:
On Linux* or macOS*, place the call into a shared library destructor.
On Windows*, call mkl_finalize from the DLL_PROCESS_DETACH handler of DllMain.
Intel® oneAPI Math Kernel Library shared libraries automatically perform finalization when they are unloaded. If an application is statically linked to Intel® oneAPI Math Kernel Library, the operating system frees all resources allocated by Intel® oneAPI Math Kernel Library during termination of the process associated with the application.
