What's the use of .map files the linker produces?

Question

What is the use of .map files VC++ linker produces when /MAP parameter or \"Generate map file\" project setting is used? When do I need them and how do I benefit from them?<

Answer 1

You need them rarely, but they can be handy debugging some problems because they give information on the location of functions and data.

For example:

• detailed information on all segments (code, data and other).
• link line numbers to code

You can use map files for debugging tools.
