WithNativePointer<THandle, TRetVal>(THandle[], ReturningOp<TRetVal>)

Marshals an array SafeHandle to a native pointer (as an array of nint)

public static TRetVal WithNativePointer<THandle, TRetVal>(this THandle[] managedArray, RefHandleMarshaller.ReturningOp<TRetVal> op) where THandle : SafeHandle

Parameters

managedArray THandle[]

Managed array of handles to marshal (by reference)

op RefHandleMarshaller.ReturningOp<TRetVal>

Operation to perform with the native array.

Returns

TRetVal

Value returned from op

Type Parameters

THandle

SafeHandle type to marshal

TRetVal

Return type of the operation

Remarks

A native nint holding array is allocated, then the managed array's handle values are copied to it (Without any AddRefs etc... the managed array OWNS the handles) before pinning the memory for the native handles and calling op

WithNativePointer<THandle>(THandle[], VoidOp)

Marshals an array SafeHandle to a native pointer (as an array of nint)

public static void WithNativePointer<THandle>(this THandle[] managedArray, RefHandleMarshaller.VoidOp op) where THandle : SafeHandle

Parameters

managedArray THandle[]

Managed array of handles to marshal (by reference)

op RefHandleMarshaller.VoidOp

Operation to perform with the native array.

Type Parameters

THandle

SafeHandle type to marshal

Remarks

A native nint holding array is allocated, then the managed array's handle values are copied to it (Without any AddRefs etc... the managed array OWNS the handles) before pinning the memory for the native handles and calling op
