The C and C++ Libraries

4.11 Tailoring other C library functions

Implementation of the following ANSI standard functions depends entirely on the target

operating system. None of the functions listed below is used internally by the library.

So if any of these functions are not implemented, only applications calling the function

directly will fail.

The target-dependent ANSI C library functions are listed in Table 4-16.

The default implementation of these functions is semihosted. That is, each function uses

the semihosting SWI.

clock()

and

_clock_init()

must be reimplemented together or not at all.
