function pointer cast

Hi, I have the following problem -

 

void dispfunc( signed long * dispval);

 

I want to call it with -

 

unsigned long testval = 0;

dispfunc( &testval );

 

Compiler, HiTech, warns illegal conversion bewteen pointer types. I would

have thought a signed and unsigned long ptr no different.

 

I tried various casts, cannot get it to work.

 

Regards, Dana.

 It compiles under Imagecraft compiler using this line:

dispfunc( (signed long *)&testval );

 

However I don't know if the generated code would be functionnal.
