LAN Manager 2.0 Network API Library Information

LAN Manager applications should be linked with libraries that contain the LAN Manager API functions. These functions reside in static-link or dynamic-link libraries (DLLs). The type of link library used depends on the operating system used by the application (MS-DOS, Microsoft Windows version 3.0, or Microsoft OS/2 version 1.1, 1.2, or 1.3).

LAN Manager operates in similar ways with OS/2, MS-DOS, and Windows, although the operating system allows more functionality when LAN Manager operates with Microsoft OS/2. OS/2 supports multiple program threads and all LAN Manager services; when installed with HPFS, OS/2 also supports long filenames. MS-DOS and Windows support only one program thread, FAT "8.3" filenames, and the Messenger, Netpopup, and Workstation services.

In systems with MS-DOS, the LAN Manager API functions reside in the static-link library DOSLAN.LIB. MS-DOS applications are linked with static-link libraries in one step at link time. Only one library is needed.

In systems with OS/2 and Windows, the LAN Manager API functions reside in the DLL file. More than one link library may be needed for these operating-system platforms, depending on the platform and the LAN Manager API functions called by the application. The Print category API functions reside in the PMSPL library; all other API functions reside in the LAN library. The following is a list of the link libraries: Note: Microsoft OS/2 and Windows do not use the same PMSPL and LAN files.
