void | wxAtomicInc (wxAtomicInt &value) |
This function increments value in an atomic manner. | |
wxInt32 | wxAtomicDec (wxAtomicInt &value) |
This function decrements value in an atomic manner. | |
wxInt32 wxAtomicDec | ( | wxAtomicInt & | value | ) |
This function decrements value in an atomic manner.
Returns 0 if value is 0 after decrement or any non-zero value (not necessarily equal to the value of the variable) otherwise.

void wxAtomicInc | ( | wxAtomicInt & | value | ) |
This function increments value in an atomic manner.
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.
