			/******************************************************************
			*
			* IMPORTANT NOTICE:
			*
			* This file is part of Android's set of stable system headers
			* exposed by the Android NDK (Native Development Kit) since
			* platform release 1.5
			*
			* Third-party source AND binary code relies on the definitions
			* here to be FROZEN ON ALL UPCOMING PLATFORM RELEASES.
			*
			* - DO NOT MODIFY ENUMS (EXCEPT IF YOU ADD NEW 32-BIT VALUES)
			* - DO NOT MODIFY CONSTANTS OR FUNCTIONAL MACROS
			* - DO NOT CHANGE THE SIGNATURE OF FUNCTIONS IN ANY WAY
			* - DO NOT CHANGE THE LAYOUT OR SIZE OF STRUCTURES
			*/

			/*
			* Support routines to send messages to the Android in-kernel log buffer,
			* which can later be accessed through the 'logcat' utility.
			*
			* Each log message must have
			* - a priority
			* - a log tag
			* - some text
			*
			* The tag normally corresponds to the component that emits the log message,
			* and should be reasonably small.
			*
			* Log message text may be truncated to less than an implementation-specific
			* limit (e.g. 1023 characters max).
			*
			* Note that a newline character ("\n") will be appended automatically to your
			* log message, if not already there. It is not possible to send several messages
			* and have them appear on a single line in logcat.
			*
			* PLEASE USE LOGS WITH MODERATION:
			*
			* - Sending log messages eats CPU and slow down your application and the
			* system.
			*
			* - The circular log buffer is pretty small (<64KB), sending many messages
			* might push off other important log messages from the rest of the system.
			*
			* - In release builds, only send log messages to account for exceptional
			* conditions.
			*
			* NOTE: These functions MUST be implemented by /system/lib/liblog.so
