OTAtomicAdd32 deprecated

MacOSX and iOS

I’m getting the repeated warning about OTAtomicAdd32 being deprecated with the 10.4 SDK. Changing juce_Atomic.h as follows fixes it:

[code]#if JUCE_MAC && ! DOXYGEN

#if (MAC_OS_X_VERSION_MAX_ALLOWED >= MAC_OS_X_VERSION_10_4)

#include <libkern/OSAtomic.h>

forcedinline void atomicIncrement (int& variable) throw()
{
    OSAtomicAdd32 (1, (int32_t*) &variable);
}

forcedinline int atomicIncrementAndReturn (int& variable) throw()
{
    return OSAtomicAdd32 (1, (int32_t*) &variable);
}

forcedinline void atomicDecrement (int& variable) throw()
{
    OSAtomicAdd32 (-1, (int32_t*) &variable);
}

forcedinline int atomicDecrementAndReturn (int& variable) throw()
{
    return OSAtomicAdd32 (-1, (int32_t*) &variable);
}

#else

forcedinline void atomicIncrement (int& variable) throw()
{
    OTAtomicAdd32 (1, (SInt32*) &variable);
}

forcedinline int atomicIncrementAndReturn (int& variable) throw()
{
    return OTAtomicAdd32 (1, (SInt32*) &variable);
}

forcedinline void atomicDecrement (int& variable) throw()
{
    OTAtomicAdd32 (-1, (SInt32*) &variable);
}

forcedinline int atomicDecrementAndReturn (int& variable) throw()
{
    return OTAtomicAdd32 (-1, (SInt32*) &variable);
}

#endif

Ah - nice one. I’d noticed that they deprecated those functions, but hadn’t got around to finding out what they changed them to yet. Cheers, matt!

…in fact, it looks like they’ve got some inc/dec functions now, so it might be a bit more efficient to use:

[code] forcedinline void atomicIncrement (int& variable) throw()
{
OSAtomicIncrement32 ((int32_t*) &variable);
}

forcedinline int atomicIncrementAndReturn (int& variable) throw()
{
    return OSAtomicIncrement32 ((int32_t*) &variable);
}

forcedinline void atomicDecrement (int& variable) throw()
{
    OSAtomicDecrement32 ((int32_t*) &variable);
}

forcedinline int atomicDecrementAndReturn (int& variable) throw()
{
   return OSAtomicDecrement32 ((int32_t*) &variable);
}

Spiffy!

It would be nice just to use the new ones, but I couldn’t get these to work with the 10.3.9 SDK.
