mkl_finalize

Terminates
Intel® oneAPI Math Kernel Library
execution environment and frees resources allocated by the library.

Syntax

void
mkl_finalize
(
void
);
Include Files
  • mkl.h
Description
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 than
mkl_finalize
.
In particular, the
mkl_finalize
function 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, call
mkl_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.
