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.

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

 Standard stream interface to Nut/OS devices.
 Low Level I/O
 Low level input and output operations.
 Time handling Functions
