C-CODE: How can I test functions with pointer arguments in cases of NULL arguments?
Last Updated 3 months ago

TPT offers the options to connect the function argument in C as value and as address.
If it is connected as value the NULL cannot be used as argument. To work around this issue, some wrapper code needs to be added.

The C/C++ Platform offers the section ‘Custom Wrapper Code’. The way to call the function with NULL is to write a special function and calling it with NULL there.

Custom WrapperCode to call the Function "callFunction(int* argument)" with NULL: 

void tpt_callFunctionNull()

A whole example is attached.
