This section describes the Microsoft Import Library Manager (IMPLIB) version 1.30. This utility creates an import library from one or more module-definition (.DEF) files and dynamic-link libraries (DLLs) for use in resolving external references from a Windows program to a DLL. IMPLIB version 1.30 is designed to use .DEF files and DLLs that work with the Microsoft Segmented Executable Linker version 5.30. IMPLIB.EXE runs under real-mode DOS.
