Function Documentation

template<typename T >

T anonymous_namespace{utils.h}::GetUnaligned

(

const void *

p

)

[inline]

Get unaligned data at specified location.

Data type indicated by template argument T.

Parameters:

p	Location of unaligned data to retrieve.

Returns:

Retrieved data from specified location.

template<typename T >

bool anonymous_namespace{utils.h}::IsPowerOf2

(

T

value

)

[inline]

Check if specified value is an integer power of two.

template<typename T >

T anonymous_namespace{utils.h}::Max	(	T	x,
		T	y
	)		[inline]

Maximal value.

template<typename T >

T anonymous_namespace{utils.h}::Min	(	T	x,
		T	y
	)		[inline]

Minimal value.

template<typename T >

void anonymous_namespace{utils.h}::PutUnaligned	(	T	value,
		void *	p
	)		[inline]

Put unaligned data at specified location.

Data type indicated by template argument T.

Parameters:

template<typename T >

T anonymous_namespace{utils.h}::RotL	(	const T	value,
		const size_t	numBits
	)		[inline]

Bit-rotate value left by specified number of bits.

Parameters:

value	Value to rotate.
numBits	Number of bits to rotate.

Returns:

Rotation result.

template<typename T >

T anonymous_namespace{utils.h}::RotR	(	const T	value,
		const size_t	numBits
	)		[inline]

Bit-rotate value right by specified number of bits.

Parameters:

value	Value to rotate.
numBits	Number of bits to rotate.

Returns:

Rotation result.

template<typename T , typename Tal >

T anonymous_namespace{utils.h}::RoundDown	(	T	size,
		Tal	align
	)		[inline]

Round down the value with specified alignment.

template<typename T , typename Tal >
