Member Function Documentation

Eof()

virtual int CefReadHandler::Eof ( )

pure virtual

Return non-zero if at end of file.

Implemented in CefByteReadHandler.

MayBlock()

virtual bool CefReadHandler::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.

Implemented in CefByteReadHandler.

Read()

virtual size_t CefReadHandler::Read ( void *  ptr, size_t  size, size_t  n  )

pure virtual

Read raw binary data.

Implemented in CefByteReadHandler.

Seek()

virtual int CefReadHandler::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.

Implemented in CefByteReadHandler.

Tell()

virtual int64_t CefReadHandler::Tell ( )

pure virtual

Return the current offset position.

Implemented in CefByteReadHandler.
