List of all members.

Public Member Functions
int	close (void)
	Close down the fifo.
ssize_t	recv (void *buf, size_t len)
	Recv buf of up to len bytes.
ssize_t	recv_n (void *buf, size_t len)
	Recv buf of exactly len bytes (block until done).
void	dump (void) const
	Dump the state of an object.
Initialization methods.
Note that ACE_NONBLOCK will be added to any flags value passed. This causes the open to succeed even if no writer has yet opened the fifo. There is no way to disable this behavior. persistent Means "open fifo for writing, as well as reading." This ensures that the fifo never gets EOF, even if there aren't any writers at the moment!
	ACE_FIFO_Recv (void)
	Default constructor.
	ACE_FIFO_Recv (const ACE_TCHAR *rendezvous, int flags=O_CREAT|O_RDONLY, mode_t perms=ACE_DEFAULT_FILE_PERMS, int persistent=1, LPSECURITY_ATTRIBUTES sa=0)
	Open up a bytestream named pipe for reading.
int	open (const ACE_TCHAR *rendezvous, int flags=O_CREAT|O_RDONLY, mode_t perms=ACE_DEFAULT_FILE_PERMS, int persistent=1, LPSECURITY_ATTRIBUTES sa=0)
	Open up a bytestream named pipe for reading.
Public Attributes
	ACE_ALLOC_HOOK_DECLARE
	Declare the dynamic allocation hooks.
Private Attributes
ACE_HANDLE	aux_handle_
	Auxiliary handle that is used to implement persistent FIFOs.
