Output Parameters
Name

Description
AllocatedBuffers
int
The number of buffers allocated by
Intel® oneAPI Math Kernel Library
.
Description
The function returns the number of buffers allocated by
Intel® oneAPI Math Kernel Library
 and the amount of memory in these buffers.
Intel® oneAPI Math Kernel Library
 can allocate the memory buffers internally or in a call tomkl_malloc/mkl_calloc. If no buffers are allocated at the moment, the
mkl_mem_stat
 function returns 0. Call
mkl_mem_stat
to check the
Intel® oneAPI Math Kernel Library
 memory status.
If you free all the memory allocated in calls to
mkl_malloc
 or
mkl_calloc
 and then call
mkl_free_buffers
, a subsequent call to
mkl_mem_stat
 normally returns 0.
