.SYNOPSIS
|
||
|
|
Generate a .lib file for linking to a dll.
|
||
|
|
.DESCRIPTION
|
||
|
|
This script generates a .lib from from a dynamic link library (dll) file.
|
||
|
|
|
||
|
|
The .lib file can then be linked against to resolve symbols in the dll file.
|
||
|
|
.PARAMETER InputBinary
|
||
|
|
The path to the dll file.
|
||
|
|
.PARAMETER OutPath
|
||
|
|
The output folder in which to save the .lib file. Defaults to the directory of the dll file.
|
||
|
|
|
||
|
|
The folder must already exist.
