[Swig-user] What is the proper typemap to marshal "bool *" in C++ as "out bool" in C#?

[Collin A. <co...@gm...>]

In the library I'm wrapping, pointer types are used effectively as out
parameters.  I'd like to construct a typemap that so that wrapping this C++
signature:

bool Func(bool* pVal)

looks like this in C#:

bool Func(out bool val)

rather than the existing:

Func(SWIGTYPE_p_bool val)

I've read through the documentation I found here
http://www.swig.org/Doc1.3/CSharp.html#csharp_memory_management_member_variables
but
the examples given are more complex, and I haven't been able to simplify
them successfully to fit my needs.  So far I've tried the following:

%typemap(cstype) bool* "out bool"

This gives me the correct signature in C#, but does not compile as the
generated code comes out like so:

  public virtual bool Func(out bool pbVal) {
    bool ret = NativePINVOKE.Func(swigCPtr, SWIGTYPE_p_bool.getCPtr(pbVal));
    return ret;
  }

error CS1503: Argument 1: cannot convert from 'bool' to 'SWIGTYPE_p_bool'

Any advice on what I'm missing here to solve this problem?

Thanks,
