; Entry points of this routine use the ^XTMP("MAGLOCK",...) global
; nodes to store lock descriptors:
;
; ^XTMP("MAGLOCK",
; 0) Standard node descriptor
; ^1: Purge date (FileMan)
; ^2: Create date (FileMan)
; ^3: Description
;
; NodeNdx) Internal lock descriptor
; ^01: Date/Time (FileMan)
; ^02: User/Process name
; ^03: User IEN (DUZ)
; ^04: $JOB
; ^05: Task number
; ^06: Lock counter
;
; The NodeNdx is calculated by the $$XLNDX^MAGUTL08 as the name
; reference to the locked node without the closing parenthesis.
;
; This routine uses the following ICRs:
;
; #2054 Get value of the DILOCKTM variable
;
Q
;
;##### LOCKS THE (SUB)FILE, RECORD OR FIELD NODE
;
; [.]FILE File/subfile number
; [IENS] IENS of the record or subfile
; [FIELD] Field number
;
; If just the FILE has a value, then the whole file is
; locked. If the FILE references a subfile, then the
; subfile IENS (the 1st ","-piece is empty) should be
; passed in the IENS parameter.
;
; If the IENS references a record of a file/subfile
; (the 1st ","-piece is not empty), then this record
; is locked.
;
; If the IENS references a record and the FIELD is
; also defined, then only the node that stores this
; field is locked.
;
; In addition (or instead) to the main locked object
; defined by the FILE, IENS, and FIELD, you can define
; several additional objects using subscripts of the
; FILE parameter:
;
; ;--- Lock the whole file #2005
; S FILE(2005)=""
; ;--- Lock the OBJECT GROUP multiple (4)
; S FILE(2005.04,",398,")=""
; ;--- Lock 2 images
; S FILE(2005,"454,")=""
; S FILE(2005,"455,")=""
; ;--- Lock just the node "40" of the image entry
; S FILE(2005,"123,",42)=""
; ;--- Lock the objects
; S RC=$$LOCKFM^MAGUTL07(.FILE)
;
; All these objects are locked at the same time. If
; even one of them cannot be locked, then nothing
; is locked.
;
; [TO] Timeout (value of DILOCKTM, by default)
;
; [NAME] Process name. If this parameter is defined and not
; empty, then its value will be returned in the lock
; descriptor instead of the user name.
;
; [FLAGS] Flags that control the execution (can be combined):
;
; D Do not actually lock the node(s); just create
; the lock descriptor(s).
;
