About microlib

3.1. About microlib

Microlib is an alternative library to the default C library. It is intended for use with deeply embedded applications that need to fit into extremely small amounts of memory. These applications do not run under an operating system.

Note

Microlib does not attempt to be a standards-compliant ISO C library.

Microlib is highly optimized for small code size. It has less functionality than the default C library and some ISO C features are completely missing. Some library functions will also be slower, for example, memcpy().
