Detailed Description

This class implements an integer that can be atomically incremented and decremented in a thread-safe manner. On Windows, the integer is of type long and this class is implemented using InterlockedIncrement and InterlockedDecrement integer is of type long. On Unix systems with GNU std++ support for EXCHANGE_AND_ADD, the integer is of type _Atomic_word (normally int) On all other systems, this class is implemented using PCriticalSection and the integer is of type int.

Member Function Documentation

bool PAtomicInteger::IsZero

(

)

const [inline]

Test if an atomic integer has a zero value. Note that this is a non-atomic test - use the return value of the operator++() or operator--() tests to perform atomic operations

Returns:

PTrue if the integer has a value of zero

long PAtomicInteger::operator++

(

)

[inline]

atomically pre-increment the integer value

Returns:

Returns the value of the integer after the increment

long PAtomicInteger::operator++

(

int

)

[inline]

atomically post-increment the integer value

Returns:

Returns the value of the integer after the increment

long PAtomicInteger::operator--

(

)

[inline]

atomically pre-decrement the integer value

Returns:

Returns the value of the integer after the decrement

long PAtomicInteger::operator--

(

int

)

[inline]

atomically post-decrement the integer value

Returns:

Returns the value of the integer after the decrement

PAtomicInteger::operator long

(

)

const [inline]

Returns:

Returns the value of the integer

void PAtomicInteger::SetValue

(

long

v

)

[inline]

Set the value of the integer

Parameters:

v	value to set
