Abstract base class for UNIX FIFOs.
UNIX FIFOs are also known Named Pipes, which are totally unrelated to Windows Named Pipes. If you want to use a local IPC mechanism that will be portable to both UNIX and Windows, take a look at the ACE_Pipe or ACE_SPIPE_Stream classes.
|
protected |
Default constructor.
Protected constructors ensure this class cannot be used directly. User code must use ACE_FIFO_Send and/or ACE_FIFO_Recv.
|
protected |
Open up the named pipe on the rendezvous in accordance with the flags.
int ACE_FIFO::close | ( | void | ) |
Close down the ACE_FIFO without removing the rendezvous point.
void ACE_FIFO::dump | ( | void | ) | const |
Dump the state of an object.
|
inline |
Return the local address of this endpoint.
int ACE_FIFO::open | ( | const ACE_TCHAR * | rendezvous, |
int | flags, | ||
mode_t | perms, | ||
LPSECURITY_ATTRIBUTES | sa = 0 |
||
) |
Open up the named pipe (FIFO) on the rendezvous point in accordance with the flags.
If flags contains O_CREAT
open() will attempt to call mkfifo() to create the FIFO before opening it. In this case, this method will not fail simply because the fifo already exists.
0 | for success |
-1 | for error; errno contains the error code. |
|
inline |
Close down the ACE_FIFO and remove the rendezvous point from the file system.
ACE_FIFO::ACE_ALLOC_HOOK_DECLARE |
Declare the dynamic allocation hooks.
|
private |
Rendezvous point in the file system.
