Default constructor creates a private group semaphores with access for OWNER_ALL.
Short | Number of semaphores in group |
Assertion | if aCount < 1 |
SemaphoreException | if kernel group create call fails. |
|
virtual |
Create a default GuardSemaphore.
SemaphoreException | if no sems left in group |
Implements corelinux::SemaphoreGroup.

virtual |
Create or open (use) a specific GuardSemaphore.
SemaphoreIdentifier | identifies which semphore id to create or attempt to use |
CreateDisposition | indicates how to treat the conditions that the group may meet in the request: CREATE_OR_REUSE indicates that the caller doesn't care FAIL_IF_EXISTS indicates the attempt was for a create FAIL_IF_NOTEXISTS indicates the attempt was for a open |
Recursive | to allow same thread multiple locks |
Balking | to allow the semaphore to balk |
SemaphoreException | if the disposition disagrees with the semaphore state, or if it is a erroneous identifier |
