TTcpOptions()

TTcpOptions ( ) [inline]

Member Functions Documentation

AlignedLength(TInt)

TInt AlignedLength ( TInt aLength ) const [private, inline]

Calculate the actual space requirement for option with given length.

Takes optional 32-bit alignment into account.

Parameters

TInt aLength

CheckOptAlignment(TUint8 *, TUint &, TUint)

void CheckOptAlignment ( TUint8 * aPtr,
TUint & aI,
TUint aNumBytes
) [private]

Align options with NOP if option alignment is enabled.

Parameters

TUint8 * aPtr option data area.
TUint & aI index to the location being processed.
TUint aNumBytes Number of bytes that need to be used for padding.

OutputOptions(TUint8 *, TUint)

IMPORT_C TUint OutputOptions ( TUint8 * aPtr,
TUint aMaxLen
) [private]

Parameters

TUint8 * aPtr
TUint aMaxLen

ProcessOptions(const TUint8 *, TUint)

IMPORT_C TBool ProcessOptions ( const TUint8 * aPtr,
TUint aLen
) [private]

Parameters

SetAlignOpt(TBool)

void SetAlignOpt ( TBool aAlignOpt ) [inline]

If set, each option will be aligned to 32-bit longword boundaries with Nop padding. By default the Nop padding is not applied.

Parameters
