Module FunctionWithWrappers

Provides predicates for identifying functions that wrap other functions, passing the same arguments from the outer call into the inner call. In the following example MyMalloc wraps a call to malloc, passing in the size parameter:

void *MyMalloc(size_t size)
{
  void *ptr = malloc(size);

  // ... additional logic?

  return ptr;
}
