The methods of this class may be called on any thread.

Member Function Documentation

◆ Flush()

virtual int CefWriteHandler::Flush ( )
pure virtual

Flush the stream.

◆ MayBlock()

virtual bool CefWriteHandler::MayBlock ( )
pure virtual

Return true if this handler performs work like accessing the file system which may block.

Used as a hint for determining the thread to access the handler from.

◆ Seek()

virtual int CefWriteHandler::Seek ( int64_t  offset,
int  whence 
)
pure virtual

Seek to the specified offset position.

|whence| may be any one of SEEK_CUR, SEEK_END or SEEK_SET. Return zero on success and non-zero on failure.

◆ Tell()

virtual int64_t CefWriteHandler::Tell ( )
pure virtual

Return the current offset position.

◆ Write()

virtual size_t CefWriteHandler::Write ( const void *  ptr,
size_t  size,
size_t  n 
)
pure virtual

Write raw binary data.
