Constructor & Destructor Documentation

LOW_semaphoreSet_SysV::LOW_semaphoreSet_SysV (  const LOW_semaphoreSetFactory::semSetIPCKey_t    inKey, const unsigned int    inSemCount, const unsigned int    inInitVal )

Constructor. Parameters: inSemSetIPCKey  Unique identifier for new shared memory segment. To get such an identifier see LOW_IPCKeyGenerator. inSemCount  Number of semaphores in set. inInitVal  Initial values of semaphores. Definition at line 37 of file LOW_semaphoreSet_SysV.cpp. References SEM_PERMS, semSetID, and semSetKey.

LOW_semaphoreSet_SysV::~LOW_semaphoreSet_SysV (    )  [virtual]

Destructor. Definition at line 66 of file LOW_semaphoreSet_SysV.cpp. References semSetID.
