MATLAB: How to make Polyspace understand a dereferenced pointer function parameter

Question

The project I'm analyzing has functions that have dereferenced pointers as the parameters:

extern void func( Custom_Type &func_param );

where "Custom_Type" is a typedef-ed struct object. Lines like this give me a

extern void func( Custom_Type &func_param );
                             ^ Expected a ")"

error in Polyspace (Bug Finder) in front of where the ampersand (&) is located. I was able to fix this error by changing the

&func_param --> * func_param

in place with the processing script option, but then that just leads to numerous errors complaining about types not matching (which makes perfect sense since the parameter type was changed).

Is there a way to inform Polyspace that the parenthesis it's expecting is at the end of the line and that the dereferenced pointer is valid?

Answer 1

Hello,

In C, this syntax

 extern void func( Custom_Type &func_param );

is not valid.

I guess that you should use the C++ mode of Polyspace, because the & character in a declaration represents a reference in C++.
