I have the following struct definition:
#ifndef struct_emxArray_real_T
#define struct_emxArray_real_T
struct emxArray_real_T
{
real_T *data;
int32_T *size;
int32_T allocatedSize;
int32_T numDimensions;
boolean_T canFreeData;
};
#endif /*struct_emxArray_real_T*/
and would like to use it in C# via PInvoke. The struct is meant to represent a matrix. Any C# struct code would be very much appreciated. Thanks!
Someone has made an attempt here :
[StructLayout(LayoutKind.Sequential, Size = 1)]
public unsafe struct mytype
{
public double* data;
public int* size;
public int allocatedSize;
public int numDimensions;
public bool canFreeData;
}
but did not get it to work.
C# structs do not support pointer types.
Instead, pointers must be ported as IntPtr
; you can use the Marshal
class to resolve the pointer.
Therefore, you should write something like
[StructLayout(LayoutKind.Sequential)]
public unsafe struct mytype
{
public IntPtr data;
public IntPtr size;
public int allocatedSize;
public int numDimensions;
public bool canFreeData;
}
Check what size your boolean_T
type is; you may need to use the [MarshalAs(...)]
attribute to specify the correct size.
