We currently have a way for you to find the SBType for "TEST" and then ask that
type for its member functions:
SBType test_type = module.FindFirstType("TEST");
const uint32_t num_member_functions = test_type.GetNumberOfMemberFunctions();
for (uint32_t i=0; i<num_member_functions; ++i)
{
SBTypeMemberFunction member_function = test_type.GetMemberFunctionAtIndex(i);
}
When using a SBFunction, you can easily get its function type:
SBFunction function = ...;
SBType function_type = function.GetType();
But there isn't a way to get directly from a SBFunction's type to
SBTypeMemberFunction. Seems like this can be fixed by adding the following
functions:
lldb::SBTypeMemberFunction lldb::SBType::GetMemberFunction();
lldb::SBTypeMemberFunction might come back invalid if the type wasn't a member
function, but if it is, then this would work.
We would also need to add a way to get the class type from the member function:
lldb::SBType lldb::SBTypeMemberFunction::GetContainingType();
This would return the class/struct that owns the member function.
So if we just add:
lldb::SBTypeMemberFunction lldb::SBType::GetMemberFunction();
lldb::SBType lldb::SBTypeMemberFunction::GetContainingType();
Then you should be able to do what you want. Let me know if you need help with
this.

You can already ask a member function for its kind:
lldb::MemberFunctionKind lldb::SBTypeMemberFunction::GetKind();
This should help for member functions.

The member function type should be correctly encoded and can be accessed by
lldb::SBTypeMemberFunction::GetKind().
