Path names in the QNTC file system

The path consists of the file system name, the server name, the share name, the directory and subdirectory names, and the object name.

The requirements for a path name are as follows:

  • The path name must begin with a slash and can be up to 255 characters long. Path names have the following form: 
         /QNTC/Servername/Sharename/Directory/ . . . /Object
(QNTC is a required part of the path name.)
  • The server name is a required portion of the QNTC path name. The server name can be a TCP/IP hostname, a NetBIOS name, or a TCP/IP address. Starting in V6R1, IPv6 addresses are supported in addition to IPv4 addresses.
  • The share name can be up to 12 characters long.
  • Each component of the path name after the share name can be up to 255 characters long.
  • Within QNTC, 130 levels of hierarchy are generally available. If all components of the path name are included as hierarchy levels, the directory hierarchy can be as many as 132 levels deep.
  • Names are stored in the Unicode CCSID.
  • By default, each supported server that is functional in the local subnet automatically appears as a directory under /QNTC. Use the Create Directory (CRTDIR) command or mkdir() API to add accessible systems located outside the local subnet.
