Argument definitions

path

is the file or directory target of the link expressed in local file system format.

location

is the file or directory target of the link. This parameter must be a relative URL using the File scheme and with the specified vfsDir object as its base.

dir

is a vfsDir object created by connecting to a network resource using either vfsConnect or vfsConnectDir.

link-path

is the name of the symbolic link in local file system format.

link-URL

is the name of the symbolic link expressed as a relative URL using the File scheme and with the specified vfsDir object as its base.

link-dir

is a vfsDir object created by connecting to a network resource using either vfsConnect or vfsConnectDir.

Use vfsLink to create a symbolic link for a file or subdirectory.

Requirements

You must include the following line at the beginning of your OmniMark program:

  include "omvfs.xin"

path must:

• exist (else external exception VFS306)
• be a file or a directory
• be expressed in local file system format
  • relative to the current directory on the local file system, or
  • as an absolute path

location must:

• exist (external exception VFS306)
• be a file or a directory
• be expressed as a relative URL based on the current working directory for dir (else external exception VFS105)

The vfsDir object dir must:

• represent an existing connection made using vfsConnect or vfsConnectDir (else external exception VFS100)
• represent a connection made using the File scheme (else external exception VFS001)

link-path must not exist (external exception VFS307).

link-URL must not exist (external exception VFS307).

The vfsDir object link-dir must:

• represent an existing connection made using vfsConnect or vfsConnectDir (else external exception VFS100)
• represent a connection made using the File scheme (else external exception VFS001)

Example

Create a symbolic link ozfile.txt to a file expressed relative to the current directory.

  include "omvfs.xin"
  
  process
    	. . .
      vfsLink "../myFiles/holland.txt"
         	to "ozfile.txt"
