On successful execution of this function: 0 is returned; on failure: an operating system-specific error code is returned.

The soft link, also known as symbolic link is a second file that exists independently of its target. The SOFTLINKFILE function returns the soft (symbolic) link file's command status. On successful execution of this function: 0 is returned; on failure: an operating system-specific error code is returned.
