Function documentation

TFileHandler(int fd, int mask)
 Create a file descriptor event handler. If mask=kRead then we
 want to monitor the file for read readiness, if mask=kWrite
 then we monitor the file for write readiness, if mask=kRead|kWrite
 then we monitor both read and write readiness.
Bool_t Notify()
 Notify when event occured on descriptor associated with this handler.
Bool_t ReadNotify()
 Notify when something can be read from the descriptor associated with
 this handler.
Bool_t WriteNotify()
 Notify when something can be written to the descriptor associated with
 this handler.
Bool_t HasReadInterest()
 True if handler is interested in read events.
Bool_t HasWriteInterest()
 True if handler is interested in write events.
void SetInterest(Int_t mask)
 Set interest mask to 'mask'.
void Add()
 Add file event handler to system file handler list.
void Remove()
 Remove file event handler from system file handler list.
TFileHandler()
{ }
virtual ~TFileHandler()
{ Remove(); }
int GetFd()
{ return fFileNum; }
void SetFd(int fd)
{ fFileNum = fd; }
void ResetReadyMask()
{ fReadyMask = 0; }
void SetReadReady()
{ fReadyMask |= 0x1; }
void SetWriteReady()
{ fReadyMask |= 0x2; }
Bool_t IsReadReady()
{ return (fReadyMask & 0x1); }
Bool_t IsWriteReady()
{ return (fReadyMask & 0x2); }
