Member Enumeration Documentation

tSeekOrigin

enum tSeekOrigin : uint8_t

Stream seek origin.

Enumerator
SO_Begin	The position origin is the beginning of the stream.
SO_Current	The position is relative to the current stream position.
SO_End	The position is relative to end of the stream.

Definition at line 99 of file stream_intf.h.

tStreamFlags

enum tStreamFlags

Stream flags.

Enumerator
SF_NONE	no flags set.

Definition at line 112 of file stream_intf.h.

Member Function Documentation

ADTF_IID()

ADTF_IID	(	IStream	,
		"stream.ant.ucom.adtf.iid"
	)

Marks the IStream to be castable with the ucom_cast<>

ADTF_IID(_interface, _striid)

Flush()

virtual tResult Flush ( )

pure virtual

Flush stream data.

The Flush method flushes all current stream data.

Returns

Returns a standard result code.

Reset()

virtual tResult Reset ( )

pure virtual

Reset stream.

The Reset method resets the stream.

Returns

Returns a standard result code.

Seek()

virtual tResult Seek ( tFilePos  nPos, tSeekOrigin  eOrigin, tFilePos *  pNewPos = nullptr  ) const

pure virtual

Set stream position.

The Seek method sets the current stream position.

Parameters

nPos	[in] Position the stream should be set to.
eOrigin	[in] Origin reference of the position value.
pNewPos	[in,out] Pointer to a variable that receives the new stream position value.

Returns

Returns a standard result code.
