◆ map_function_parameters_to_function_argument_names()

std::unordered_set< irep_idt > function_call_harness_generatort::implt::map_function_parameters_to_function_argument_names ( )

For function parameters that are pointers to functions we want to be able to specify whether or not they can be NULL.

To disambiguate this specification from that for a global variable of the same name, we prepend the name of the function to the parameter name. However, what is actually being initialised in the implementation is not the parameter itself, but a corresponding function argument (local variable of the harness function). We need a mapping from function parameter name to function argument names, and this is what this function does.
