Signed integer type of the natural machine word length.
This is as defined by the C++ implementation's int type. In all
implementations, this is guaranteed to be at least 32 bits.
A TInt should be used in preference to a sized integer (TInt32, TInt16) for
all general use. Sized integers should only be used when packing is essential.
C++'s type conversion rules imply that all sized integers smaller than the
natural machine word are in any case broadened to the natural machine word
size when passed as function parameters.
A TInt should be used in preference to an unsigned integer (TUint) for all
general use. Unsigned integers should only be used for flags (which use Boolean
operations but not arithmetic) and, in very rare cases, for numbers whose
range exceeds that available from signed integers. Although it is natural
to attempt to use unsigned integers for quantities which cannot by nature
be negative, the C++ language does not provide the support necessary to enforce
the "expected" behaviour in these circumstances, and experience has shown
that it is better to use signed integers unless there is good reason not to.

Defines a 64-bit signed integer type.
NOTE: For those migrating from versions of Symbian OS before 8.1b (i.e. 8.1a, 7.0s etc)
TInt64 is now defined as a built-in type instead of as a class type. This means
that the member functions of the old TInt64 class are no longer exported
from EUSER.LIB, and represents a compatibility break.
To ease migration of source code, a number of macros are provided. Similar
macros have also been defined in Symbian OS versions 7.0s and 8.1a, but
implemented in terms of the old TInt64 class. This is important for code that
is common to : one or both of these Symbian OS versions, and to 8.1b and
subsequent versions.
The following list shows the new macros and the functions that they replace.
It also shows some alternative techniques.
In this list: x, v and r are declared as TInt64, c is declared as TInt, High
and Low are declared as TUint.

Asserts that a condition is true.
Code is generated for all builds.
This macro is used as a C++ statement to assert the truth of some condition,
and to take appropriate action if the condition is false. Unlike __ASSERT_DEBUG
it is defined in both release and debug builds.
The most common use for this macro is to check that the external environment of
a function or class is behaving as expected; for example, that parameters
passed to a function are credible, or that called functions are behaving as
expected; the macro is commonly placed at the beginning of a function.
The effect of the macro is to generate code which tests
the conditional expression c; if the expression is false, then
function p is called. In the majority of cases, the function p is one that
raises a panic.
Note that the macro definition is, in effect, equivalent to:
@code
if !(c)p;
@endcode
@param c a conditional expression which results in true or false.
@param p a function which is called if the conditional expression c is false.

Calls the function for testing object invariance.
Classes can define a standard member function __DbgTestInvariant(),
which checks that the object is in a valid state, and panics if it is not.
In debug builds, this macro simply expands to call that function. For details on how
to define __DbgTestInvariant(), and an example of its use, see __DECLARE_TEST.
The macro is typically invoked at the beginning of all the member functions of
the class. For non-const functions (those which can change the object’s state),
you can ensure that the object has been left in a stable state by invoking
the macro at the end of the function.
In release builds, no code is generated for the macro.

Declares a function for testing object invariance.
For complex classes, it is often useful to provide a function that can
be called to check that the object is in a valid state.
The __DECLARE_TEST macro supplies a standard prototype for such a function
named __DbgTestInvariant(). A companion macro __TEST_INVARIANT is provided
to call the function.
For DLLs, as opposed to EXEs, __DbgTestInvariant() is exported,
i.e. the macro expands to:
@code
public: IMPORT_C void __DbgTestInvariant() const; void __DbgTest(TAny *aPtr) const
@endcode
This macro should placed as the last item in a class declaration (as it
switches back to public access). Note that a terminating semi-colon must be used.
You should define the __DbgTestInvariant() function to check that the object
is in a healthy state. If it finds an error, it should call User::Invariant(),
which will cause a panic.
If a class is derived from a base class, then the base class __DbgTestInvariant()
should be called first, and then any further checking done.
The second function declared, __DbgTest(), is intended to allow test code a way
of directly accessing non-public members of a class. The function is
implemented by any test code that requires it, rather than in the class’s own
source code. The function is therefore not exported.
__DECLARE_TEST is defined for both debug and release builds. This point is
particularly important for DLLs, as otherwise the exported interfaces would
differ between the build versions, giving potential binary compatibility
problems. To avoid using memory unnecessarily in release builds, you can,
however, use preprocessor directives to define the code within
__DbgTestInvariant() only for debug builds. __DbgTestInvariant() is never
called in release builds.

/**

A macro that should be used to enclose a platform security diagnostic
'C' style string that can be passed to a capability checking function such
as RThread::HasCapability() and Kern::CurrentThreadHasCapability().
The content of the string is emitted if the capability test finds that
the capability is not present.
The macro provides a convenient mechanism that allows the strings to
be removed from future versions of Symbian OS.
For example:
@code
if(!Kern::CurrentThreadHasCapability(ECapabilityPowerMgmt,__PLATSEC_DIAGNOSTIC_STRING("Checked by Hal function EDisplayHalSetState")))
{
return KErrPermissionDenied;
}
@endcode
In this example, the string:
@code
Checked by Hal function EDisplayHalSetState
@endcode
is emitted if the calling process does not have the ECapabilityPowerMgmt capability.
@param s A C-style string.
@see RProcess::HasCapability()
@see RThread::HasCapability()
@see RMessagePtr2::HasCapability()
@see User::CreatorHasCapability()
