$RENAME

You can use this service to change the name, type, or version of a file, or to move a file to another directory by changing its directory specification. However, note that you cannot use this service to move a file to another device.

Format

SYS$RENAME old-fab ,[err] ,[suc] ,new-fab


RETURNS


OpenVMS usage: cond_value
type: longword
access: write only
mechanism: by value

The value is returned in symbolic offset FAB$L_STS. Symbolic offset FAB$L_STV may contain additional status information.


Arguments

old-fab


OpenVMS usage: fab
type: longword (unsigned)
access: modify
mechanism: by reference

FAB control block whose contents are to be used as indirect arguments for the Rename service call. The old-fab argument is the address of the FAB control block that specifies the old file name.

err


OpenVMS usage: ast_procedure
type: procedure value
access: call without stack unwinding
mechanism: by reference

AST-level error completion routine that the service invokes if the operation is unsuccessful. The err argument is the address of the entry mask of this user-written completion routine.

suc


OpenVMS usage: ast_procedure
type: procedure value
access: call without stack unwinding
mechanism: by reference

AST-level success completion routine that the service invokes if the operation is successful. The suc argument is the address of the entry mask of this user-written completion routine.

new-fab


OpenVMS usage: fab
type: longword (unsigned)
access: modify
mechanism: by reference

The new-fab argument is the address of the FAB control block that specifies the new file name.

Note

If you invoke the Rename service using the $RENAME macro and if you do not specify arguments, you must construct an additional field within your argument list to contain the address of the FAB that specifies the new file name. This additional field is placed in the argument list following the field for the success completion routine (see Part 1), and the argument count is set to 4.

Description

The Rename service performs the equivalent of two Parse services (old and new name), a Search service for the old directory, an Enter service to insert the new file name into the new directory, and a Remove service to delete the old file name from the old directory.

No wildcard character specifications are allowed. You can move a file from one directory to another using this service, but both directories must be on the same disk device.

If the Rename service is successful, the new directory entry is created and the old entry is deleted. If the service fails, the old entry remains and the new entry is deleted.

The following tables list the fields in FAB, NAM, and NAML blocks that the Rename service uses as input and output. In these tables, these blocks are called FAB1 and NAM1 for the old entry, and FAB2 and NAM2 for the new entry. For output, FAB2 is not used, although it must be in writable memory. To check or signal the completion codes in FAB$L_STS and FAB$L_STV, use the first FAB (FAB1).

The resultant file specification string for each of the names (old and new) is placed in the buffer described by the NAM$L_RSA (or NAML$L_LONG_RESULT) and NAM$B_RSS (or NAML$_LONG_RESULT_ALLOC) fields of the separate NAM or NAML blocks (only if both fields are nonzero).

Table RMS-77 lists the FAB control block fields read as input by the Rename service. For additional information on the fields accessed by this service, see Part 2.

Table RMS-77 Rename Service FAB Input Fields
Control Block Field Name Description
FAB1 and FAB2 FAB$L_DNA Default file specification string address.
  FAB$B_DNS Default file specification string size.
  FAB$L_FNA File specification string address.
  FAB$B_FNS File specification string size.
  FAB$W_IFI Internal file identifier (must be zero).
  FAB$L_NAM NAM or NAML block address.

Table RMS-78 lists the FAB control block fields written as output by the Rename service.

Table RMS-78 Rename Service FAB Output Fields
Control Block Field Name Description
FAB1 FAB$L_STS Completion status code (also returned in register 0).
  FAB$L_STV Status value.
