===========================================================================================
This is the header file for version 2.2 of the Mac OS multiprocessing support. This version
has been totally reimplemented and has significant new services. The main goal of the
reimplementation has been to transfer task management into the core operating system to provide
much more reliable and more efficient operation, including on single processor machines.
The memory management has also been massively improved, it is much faster and wastes much
less space. New services include POSIX style per-task storage, timers with millisecond and
microsecond resolutions, memory allocation at a specified alignment, and system pageable
and RAM resident memory pools. See the MP API documentation for details.
The old "DayStar" debugging services (whose names began with an underscore) have been
removed from this header. A very few are still implemented for binary compatibility, or in
cases where they happened to be exposed inappropriately. (E.g. _MPIsFullyInitialized must
be called to see if the MP API is ReallyTruly(tm) usable.) New code and recompiles of old
code should avoid use of these defunct services, except for _MPIsFullyInitialized.

*** Important Note ***
----------------------
The functions MPExtractTaskState and MPSetTaskState infer the size of the "info" buffer
from the "kind" parameter. A given value for MPTaskStateKind will always refer to a
single specific physical buffer layout. Should new register sets be added, or the size
or number of any registers change, new values of MPTaskStateKind will be introduced to
refer to the new buffer layouts.
The following types for the buffers are in MachineExceptions. The correspondence between
MPTaskStateKind values and MachineExceptions types is:
kMPTaskStateRegisters -> RegisterInformation
kMPTaskStateFPU -> FPUInformation
kMPTaskStateVectors -> VectorInformation
kMPTaskStateMachine -> MachineInformation
kMPTaskState32BitMemoryException -> ExceptionInfo for old-style 32-bit memory exceptions
For reference, on PowerPC the MachineExceptions types contain:
RegisterInformation -> The GPRs, 32 values of 64 bits each.
FPUInformation -> The FPRs plus FPSCR, 32 values of 64 bits each, one value of
32 bits.
VectorInformation -> The AltiVec vector registers plus VSCR and VRSave, 32 values
of 128 bits each, one value of 128 bits, and one 32 bit value.
MachineInformation -> The CTR, LR, PC, each of 64 bits. The CR, XER, MSR, MQ,
exception kind, and DSISR, each of 32 bits. The 64 bit DAR.
ExceptionInfo -> Only memory exceptions are specified, 4 fields of 32 bits each.
Note that this type only covers memory exceptions on 32-bit CPUs!
The following types are declared here:
kMPTaskStateTaskInfo -> MPTaskInfo

Checking API Availability
=========================
*/
/*
===========================================================================================
*** WARNING: You must properly check the availability of MP services before calling them!
===========================================================================================
Checking for the availability of the MP API is rather ugly. This is a historical problem,
caused by the original implementation letting itself get prepared when it really wasn't
usable and complicated by some important clients then depending on weak linking to "work".
(And further complicated by CFM not supporting "deferred" imports, which is how many
programmers think weak imports work.)
The end result is that the MP API library may get prepared by CFM but be totally unusable.
This means that if you import from the MP API library, you cannot simply check for a
resolved import to decide if MP services are available. Worse, if you explicitly prepare
the MP API library you cannot assume that a noErr result from GetSharedLibrary means that
MP services are available.
o If you import from the MP API library you MUST:
Use the MPLibraryIsLoaded macro (or equivalent code in languages other than C) to tell
if the MP API services are available. It is not sufficient to simply check that an
imported symbol is resolved as is commonly done for other libraries. The macro expands
to the expression:
( ( (UInt32)_MPIsFullyInitialized != (UInt32)kUnresolvedCFragSymbolAddress ) &&
( _MPIsFullyInitialized () ) )
This checks if the imported symbol _MPIsFullyInitialized is resolved and if resolved
calls it. Both parts must succeed for the MP API services to be available.
o If you explicitly prepare the MP API library you MUST:
Use code similar to the following example to tell if the MP API services are available.
It is not sufficient to depend on just a noErr result from GetSharedLibrary.
OSErr err;
Boolean mpIsAvailable = false;
CFragConnectionID connID = kInvalidID;
MPIsFullyInitializedProc mpIsFullyInitialized = NULL;
err = GetSharedLibrary ( "\pMPLibrary", kCompiledCFragArch, kReferenceCFrag,
&connID, NULL, NULL );
if ( err == noErr ) {
err = FindSymbol ( connID, "\p_MPIsFullyInitialized",
(Ptr *) &mpIsFullyInitialized, NULL );
}
if ( err == noErr ) {
mpIsAvailable = (* mpIsFullyInitialized) ();
}
