The Main Standard Libraries (MSL) are a complete, configurable set of C and C++ standard libraries. These libraries also include MSL Extras, which extends the standard library and adds compatibility with common UNIX libraries. All of the source files required to build MSL are included in your CodeWarrior product, along with project files for different MSL configurations.
To use the MSL library, you must also use a runtime library. To support custom hardware capabilities, such as a new memory configuration, make changes to the runtime libraries instead of the MSL library's source files. Then, if necessary, reconfigure and recompile the MSL library. Refer to the MSL C Reference or MSL C++ Reference for more information.
