The following information is from "Section 5: Creating Dynamic-Link
Libraries" of the Microsoft C version 5.10 MTDYNA.DOC file.

Creating Dynamic-Link Libraries

You can create the following two types of dynamic-link libraries with
this release of C:

1. A stand-alone, single-thread dynamic-link library

2. A C run-time dynamic-link library that supports multiple threads
   and is itself dynamically linked.

The stand-alone dynamic-link library is independent of the calling
program and is single thread only and statically linked. This isolated
dynamic-link library is independent of the effects of other
dynamic-link libraries and can be viewed conceptually as an extension
of the operating system. Use the OS/2 support library, LLIBCDLL.LIB, a
large-model, single-thread C run-time library for creating
single-thread dynamic-link libraries. LLIBCDLL.LIB is statically
linked and uses only the alternate math library.

The dynamically-linked C run-time library may be used by a
multiple-thread program and an optional group of dynamic-link
libraries that are closely associated with it. Use the OS/2 support
library, CDLLOBJS.LIB to create a C run-time library that is
dynamically linked.

Dynamic-link libraries can be debugged with the protected-mode
CodeView debugger (CVP). For more information on this topic, see
Section 2.2.2 "Debugging Dynamic-Link Modules" in the Microsoft
CodeView and Utilities Update document.
