Overview of LIB 

LIB creates standard libraries, import libraries, and export files you can use with LINK when building a 32-bit program. LIB runs from a command prompt.

You can use LIB in the following modes:

• Building or modifying a COFF library

• Extracting a member object to a file

• Creating an export file and an import library

These modes are mutually exclusive; you can use LIB in only one mode at a time.
