C Runtime Library.

---

Detailed Description

Complementary runtime support.

Normal C language runtime libraries are too large for small embedded systems and many functions require an underlying operating system. Compilers for the AVR provide a limited subset only, which do not include sufficient device support.

Nut/OS includes its own runtime library. When linked with an application, this library partly overrides the standard library which comes with your compiler.

Warning:

Using these functions requires to link nutcrt or nutcrtf before the compiler's standard libraries.

Modules
	Standard I/O
	Standard stream interface to Nut/OS devices.
	Low Level I/O
	Low level input and output operations.
	Time handling Functions
	Implements some standard C time functions.
	Miscellaneous Functions
	Complementary runtime support.
