SysSemDelete (FUN) ¶ FUNCTION SysSemDelete : RTS_IEC_RESULT This function deletes the semaphore which is identified by its handle. InOut: Scope Name Type Comment Return SysSemDelete RTS_IEC_RESULT Return the runtime system error code (see CmpErrors.library) Input hSem RTS_IEC_HANDLE Handle of the semaphore

SysRWLReadLock (FUN) ¶ FUNCTION SysRWLReadLock : RTS_IEC_RESULT This function to enter a read lock(synchronization object). NOTE: Several readers can enter the lock simultaneously! But they are synchronized against an entered write lock! RETURN: Returns the runtime system error code (see CmpErrors.library) InOut: Scope Name Type Comment Return SysRWLReadLock RTS_IEC_RESULT Input hRWLock RTS_IEC_HANDLE Handle to the ReadWrite lock object created by SysRWLCreate

SysRWLReadLockTry (FUN) ¶ FUNCTION SysRWLReadLockTry : RTS_IEC_RESULT This function tries enter a read lock(synchronization object). If a write lock is still active, the functions returns an error. The function succeeded as well, if another read lock is still active. NOTE: Several readers can enter the lock simultaneously! But they are synchronized against an entered write lock! RETURN: Returns the runtime system error code (see CmpErrors.library) InOut: Scope Name Type Comment Return SysRWLReadLockTry RTS_IEC_RESULT Input hRWLock RTS_IEC_HANDLE Handle to the ReadWrite lock object created by SysRWLCreate
