Static Public Member Functions

static IoStreamFileRef createRef (FILE *file, bool ownsFile=true, int32_t defaultBufferSize=2048)
 Creates a new IoStreamFileRef from a C-style file pointer FILE as returned by fopen(). If ownsFile the returned stream will destroy the stream upon its own destruction.

Member Function Documentation

IoStreamFileRef cinder::IoStreamFile::createRef ( FILE *  file,
bool  ownsFile = true,
int32_t  defaultBufferSize = 2048 
) [static]

Creates a new IoStreamFileRef from a C-style file pointer FILE as returned by fopen(). If ownsFile the returned stream will destroy the stream upon its own destruction.

size_t cinder::IoStreamFile::readDataAvailable ( void *  dest,
size_t  maxSize 
) [virtual]

Implements cinder::IStream.

void cinder::IoStreamFile::seekAbsolute ( off_t  absoluteOffset  )  [virtual]

Sets the current position of the stream to byte absoluteOffset. A negative offset is relative to the end of the file.

Implements cinder::StreamBase.

void cinder::IoStreamFile::seekRelative ( off_t  relativeOffset  )  [virtual]

Moves the current position of the stream by relativeOffset bytes.

Implements cinder::StreamBase.

off_t cinder::IoStreamFile::tell (  )  const [virtual]

Returns the current position of the stream measured in bytes **/.

Implements cinder::StreamBase.

off_t cinder::IoStreamFile::size (  )  const [virtual]
