SetMailslotInfo
The SetMailslotInfo function sets the time-out value used by the specified mailslot for a read
operation.
BOOL SetMailslotInfo(
HANDLE hMailslot,
| // mailslot handle
| DWORD lReadTimeout
| // read time-out
| );
|
|
Parameters
hMailslot
Identifies a mailslot. The CreateMailslot function must create this handle.
lReadTimeout
Specifies the amount of time, in milliseconds, a read operation can wait for a
message to be written to the mailslot before a time-out occurs. The following
values have special meanings:
Value
| Meaning
| 0
| Returns immediately if no message is present. (The system does not treat an
immediate return as an error.)
| MAILSLOT_WAIT_FOREVER
| Waits forever for a message.
|
This time-out value applies to all subsequent read operations and to all
inherited mailslot handles.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error
information, call GetLastError.
Remarks
The initial time-out value used by a mailslot for a read operation is
typically set by CreateMailslot when the mailslot is created.
