Member Function Documentation

Align()

template<typename T >

T * CppCommon::Memory::Align ( const T *  address, size_t  alignment = alignof(T), bool  upwards = true  )

inlinestaticnoexcept

Align pointer (upwards or downwards)

Parameters

address	- Address
alignment	- Alignment value. Must be a pointer of two (default is alignof(T))
upwards	- Upwards flag (default is true)

Returns

Aligned address

Definition at line 29 of file memory.inl.

CryptoFill()

void CppCommon::Memory::CryptoFill ( void *  buffer, size_t  size  )

static

Fill the given memory buffer with cryptographic strong random bytes.

Parameters

buffer	- Memory buffer to fill
size	- Size of memory buffer in bytes

Definition at line 136 of file memory.cpp.

IsAligned()

template<typename T >

bool CppCommon::Memory::IsAligned ( const T *  address, size_t  alignment = alignof(T)  )

inlinestaticnoexcept

Is the given pointer aligned?

Parameters

address	- Address
alignment	- Alignment value. Must be a pointer of two (default is alignof(T))

Returns

'true' if the given address is aligned, 'false' if the given address is not aligned

Definition at line 19 of file memory.inl.

IsValidAlignment()

bool CppCommon::Memory::IsValidAlignment ( size_t  alignment )

inlinestaticnoexcept

Is the given alignment valid?

Parameters

alignment

- Alignment value. Must be a power of two.

Returns

'true' if the given alignment is valid, 'false' if the given alignment is not valid

Definition at line 13 of file memory.inl.

IsZero()

bool CppCommon::Memory::IsZero ( const void *  buffer, size_t  size  )

staticnoexcept

Is the given memory buffer filled with zeros?

Parameters

buffer	- Memory buffer
size	- Size of memory buffer in bytes

Returns

'true' if the given memory buffer is filled with zeros, 'false' if the memory buffer is not filled with zeros

Definition at line 95 of file memory.cpp.
