Profiling a dynamic-link library (DLL) is similar to profiling an .EXE file. When you profile a DLL, you follow the same steps and use the same commands that you would for an .EXE file. The same profiling rules that apply to .EXE files (such as the need to include debugging information and to supply a .MAP file) apply to DLLs.
