MKL_malloc interface missing from Fortran module

Hi,

It looks like the interface for MKL_malloc is missing from the mkl_service Fortran 90 module, at least in the versions I have. Is it supposed to be in there? The documentation seems to indicate so, and the interface for mkl_free is definitely there.

Cheers,
Ben

declared in mkl_service.h.

declared in mkl_service.h. there is an example -- <mklroot>\examples\servicefuncsf\source\ servicefuncs.f

Yes, the C prototypes are in mkl_service.h, but that won't work for Fortran.

That example file has the MKL memory functions declared as external, rather than with using an explicit interface:

#ifdef _IA32
      INTEGER*4 MKL_MALLOC, MKL_CALLOC, MKL_REALLOC
      integer*4 ALLOC_SIZE, NUM_ELEM, SIZE_ELEM
#else
      INTEGER*8 MKL_MALLOC, MKL_CALLOC, MKL_REALLOC
      integer*8 ALLOC_SIZE, NUM_ELEM, SIZE_ELEM
#endif

      EXTERNAL   MKL_MALLOC, MKL_FREE, MKL_CALLOC, MKL_REALLOC

The documentation indicates that an interface should be available for both languages:

However it's also missing from mkl.fi:

I just wrote my own interface for it.

Hello.

The issue has been fixed in MKL v.11.3.0 which has been released two days ago. Please check how it works and let us know if any further problems.
