Tailoring the C library to a new execution environment involves re-implementing functions to produce an application for a new execution environment, for example, embedded in ROM or used with an RTOS.
Symbols that start with a single or double underscore name
functions that are used as part of the low-level implementation.
You can re-implement some of these functions. Additional information
on these library functions is available in the
rt_sys.h include files and the
