Detailed Description

Writes data to files on disc.

Constructor & Destructor Documentation

◆ decDiscFileWriter()

decDiscFileWriter::decDiscFileWriter ( const char *  filename,
bool  append 
)

Create file reader object for the file.

The file is opened immediatly for writing. The filename specified has to be an absolute path.

Exceptions
deeInvalidParamfilename is NULL.
deeFileNotFoundfilename can not be opened for writing.

◆ ~decDiscFileWriter()

virtual decDiscFileWriter::~decDiscFileWriter ( )
protectedvirtual

Close file and clean up.

Note
Subclasses should set their destructor protected too to avoid users accidently deleting a reference counted object through the object pointer. Only FreeReference() is allowed to delete the object.

Member Function Documentation

◆ GetFilename()

virtual const char* decDiscFileWriter::GetFilename ( )
virtual

Name of the file.

Implements decBaseFileWriter.

◆ Write()

virtual void decDiscFileWriter::Write ( const void *  buffer,
int  size 
)
virtual

Write size bytes from buffer and advances the file pointer.

Exceptions
deeInvalidParambuffer is NULL.
deeInvalidParamsize is less than 0.
deeWriteFileCan not write to file.

Implements decBaseFileWriter.
