mwPointer (Fortran) - Declare appropriate pointer type for platform
Description
mwPointer is a preprocessor macro that declares
the appropriate Fortran type representing a pointer to an mxArray or
to other data that is not of a native Fortran type, such as memory
allocated by mxMalloc. On 32-bit platforms, the
Fortran type that represents a pointer is INTEGER*4;
on 64-bit platforms, it is INTEGER*8. The Fortran
preprocessor translates mwPointer to the Fortran
declaration that is appropriate for the platform on which you compile
your file.
If your Fortran compiler supports preprocessing, you can use mwPointer to
declare functions, arguments, and variables that represent pointers.
If you cannot use mwPointer, you must ensure that
your declarations have the correct size for the platform on which
you are compiling Fortran code.
The Fortran header file containing this type is:
#include "fintrf.h"
Examples
This example declares the arguments for mexFunction in a Fortran MEX-file:
SUBROUTINE MEXFUNCTION(NLHS, PLHS, NRHS, PRHS)
MWPOINTER PLHS(*), PRHS(*)
INTEGER NLHS, NRHS
For additional examples, see the Fortran files with names ending
in .F in the matlabroot/extern/examples folder.
