Problem while generating a pointer to a struct (a field of the struct is a pointer to a function)

I would like to create a pointer to a struct and then use it as an input in *.dll function call. Some fields of the struct are numbers but a few of them are function pointers (fcnPtr).
Please have a look in below pseudo-code:
loadlibrary('myLib.dll', 'my_header.h', 'mfilename', 'myLibbit.m')
myStruct.dev_id = uint8(1);
myStruct.read = @myReadFunction; % Function handle
myStructMatlab = libstruct('struct_name', myStruct);
myStructMatlabPt = libpointer('struct_namePtr', myStructMatlab);
I get the following error:
Cannot convert data value for field read due to error:
Array must be numeric or logical or a pointer to one
Error in libstruct (line 16)
ptr=feval(['lib.' structtype],initialvalue);
In case that I do not use the field myStruct.read the above process works fine. Is there a way to solve the above issue?
