Portability Function: Renames a file.
USE IFPORT
result = RENAME (from,to)
from |
(Input) Character*(*). Path of an existing file. |
to |
(Input) Character*(*). The new path for the file (see Caution note below). |
The result type is INTEGER(4). The result is zero if successful; otherwise, an error code, such as:
EACCES - The file or directory specified by to could not be created (invalid path). This error is also returned if the drive specified is not currently connected to a device.
ENOENT - The file or path specified by from could not be found.
EXDEV - Attempt to move a file to a different device.
This routine can cause data to be lost. If the file specified in to already exists, RENAME deletes the pre-existing file.
It is possible to rename a file to itself without error.
The paths can use forward (/) or backward (\) slashes as path separators and can include drive letters (if permitted by your operating system).
