◆ ConvertToString()

StrLen_t Gray::cMemBlock::ConvertToString ( char *  pszDst,
StrLen_t  iDstSizeMax 
) const
inline

◆ get_Data()

void* Gray::cMemBlock::get_Data ( ) const
inlinenoexcept

Might be nullptr. that's OK.

◆ get_DataA()

char* Gray::cMemBlock::get_DataA ( ) const
inlinenoexcept

Get as a char pointer.

◆ get_DataBytes()

BYTE* Gray::cMemBlock::get_DataBytes ( ) const
inlinenoexcept

Get as a BYTE pointer.

◆ get_DataEnd()

const void* Gray::cMemBlock::get_DataEnd ( ) const
inlinenoexcept

Never write to this pointer.

◆ get_DataSize()

size_t Gray::cMemBlock::get_DataSize ( ) const
inlinenoexcept

◆ GetOffset()

BYTE* Gray::cMemBlock::GetOffset ( size_t  nOffset) const
inline

Get as a byte pointer.

◆ InitZeros()

void Gray::cMemBlock::InitZeros ( )
inlinenoexcept

◆ IsEqualData() [1/3]

bool Gray::cMemBlock::IsEqualData ( const cMemBlock &  data) const
inlinenoexcept

compare blocks of data.

◆ IsEqualData() [2/3]

bool Gray::cMemBlock::IsEqualData ( const cMemBlock *  pData) const
inlinenoexcept

compare blocks of data.

◆ IsEqualData() [3/3]

compare blocks of data.

◆ IsValidIndex()

bool Gray::cMemBlock::IsValidIndex ( size_t  i) const
inlinenoexcept

Is i inside the known valid range for the block?

◆ IsValidIndex2()

bool Gray::cMemBlock::IsValidIndex2 ( size_t  i) const
inlinenoexcept

Is i inside the known valid range for the block? or at end?

◆ isValidPtr()

bool Gray::cMemBlock::isValidPtr ( ) const
inlinenoexcept

Is this (probably) valid to use/read/write. not nullptr. Use cMem::IsValid to know more.

◆ IsValidPtr()

bool Gray::cMemBlock::IsValidPtr ( const void *  p) const
inlinenoexcept

Is p inside the known valid range for the block? Inclusive = Can be equal to end.

◆ IsValidPtr2()
