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).
