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;
}

Imports

PrintfLike	Provides a predicate for identifying formatting functions like `printf`.
cpp	Provides classes and predicates for working with C/C++ code.

Classes

FunctionWithWrappers	An abstract class for representing functions that may have wrapper functions. Wrapper functions propagate an argument (without any evident changes) to this function through one or more steps in a call chain.
PrintfLikeFunction	A `printf`-like formatting function.
