This section presents information programmers should be aware of when using LAN Server APIs with DOS LAN Services (DLS).

In this section, you will find information about:

• IBM DLS API services
  
• IBM DLS libraries, where they are stored, and which ones are needed for particular APIs
  
• API functions supported under IBM DLS and any differences in their use

Note: A DLS peer workstation does not participate in any OS/2 LAN Server domain. It works like an OS/2 server in a role of standalone or an OS/2 Peer workstation. Also, it cannot be administered by using the NET ADMIN command from a remote node. However, a user can administer a DLS peer workstation remotely from another DLS workstation or an OS/2 requester or server. When porting LAN Server applications to run under DLS, be aware that DOS, unlike the OS/2 operating system, does not support pointer checking, semaphores, or shared memory segments. All file names, directory names, or parts of a path name, including UNC server and share names, must follow DOS naming conventions.

Most of the LAN Server APIs are accessible from a DLS workstation. Except in several cases, such as the Handle, Mailslot, Named Pipe, and other DOS-supported APIs, calls to the APIs described in this book can be issued from a DLS workstation only to remote OS/2 LAN servers.
