VSMBK Prolog
Name : HCPVSMBK Description: Vtam Service Machine control BlocK STATUS : VM/ESA Version 2, Release 2.0 DSECT : VSMBK Function : This block is used to contain information about a single Vtam Service Machine. Located by : SYSVSMBK - Anchor for the system VSMBK queue (located in SYSCM). VSMNEXT - VSMBK forward chain pointer (located in VSMBK). Created by : HCPVCLDV - DISABLE SNA command processor for a specific VSM HCPVCLEV - ENABLE SNA command processor for a specific VSM HCPVCTCN - VSM global IUCV CONNECT processor Deleted by : HCPVCZRL - SNABK/RDEV and VSMBK storage releaser Serialized : The updating of all fields in this block is serialized by exclusive ownership of the system vtam service machine lock (SYSVSMLK) located in SYSCM. Interrogation of a field without the lock is permitted as long as no action is taken which could be invalidated by that field's value changing the instant after it was obtained. Otherwise interrogation requires at least a share of the lock.
