C Library - - Tutorialspoint
The ctype.h header file of the C Standard Library declares several functions that are useful for testing and mapping characters. All the functions accepts int as a parameter, whose value must be EOF or representable as an unsigned char.
CType Function - Visual Basic | Microsoft Docs
CType(expression, typename) Parts. expression Any valid expression. If the value of expression is outside the range allowed by typename, Visual Basic throws an exception. typename Any expression that is legal within an As clause in a Dim statement, that is, the name of any data type, object, structure, class, or interface.

Passing pointers (or: passing parameters by reference)¶ Sometimes a C api function expects a pointer to a data type as parameter, probably to write into the corresponding location, or if the data is too large to be passed by value. This is also known as passing parameters by reference.. ctypes exports the byref() function which is used to pass parameters by reference.
(ctype.h) - C++ Reference
(ctype.h) Character handling functions. This header declares a set of functions to classify and transform individual characters. Functions These functions take the int equivalent of one character as parameter and return an int that can either be another character or a value representing a boolean value: ...

std::ctype - cppreference.com
Class ctype encapsulates character classification features. All stream input operations performed through std:: basic_istream < charT > use the std:: ctype < charT > of the locale imbued in the stream to identify whitespace characters for input tokenization. Stream output operations apply std:: ctype < charT >:: widen to narrow-character arguments prior to output.

ctypes · PyPI
ctypes is a Python package to create and manipulate C data types in Python, and to call functions in dynamic link libraries/shared dlls. It allows wrapping these libraries in pure Python.
