/**
This function increments @a value in an atomic manner.
@note It is recommended to use @c std::atomic available in C++11 and later
instead of this function in any new code.
Whenever possible wxWidgets provides an efficient, CPU-specific,
implementation of this function. If such implementation is available, the
symbol wxHAS_ATOMIC_OPS is defined. Otherwise this function still exists
but is implemented in a generic way using a critical section which can be
prohibitively expensive for use in performance-sensitive code.
Returns the new value after the increment (the return value is only
available since wxWidgets 3.1.7, this function doesn't return anything in
previous versions of the library).

This function decrements value in an atomic manner.
Returns the new value after decrementing it.
