The Metrowerks Standard Library (MSL) C++ stream-based classes will initialize several instances of direct and indirect objects. When code size is critical, do not use any stream-based classes. The stream-based classes include standard input (cin), standard output (cout), and standard error (cerr). There are wide-character equivalents for the normal input and output routines as well. Unless there is a great need for these classes, use standard C input and output functions instead.

In addition to the standard C++ stream classes, there are string streams for in-core formatting that will also evoke a heavy overhead and should be avoided. If size is critical, use C's sprintf or sscanf functions instead.

The proposal for Embedded C++ does not allow for templatized classes or functions. MSL is compliant with the ANSI/ISO proposed standards that are based on templates.
