Function Documentation

void NutInit (  void    )

Nut/OS Initialization. Initializes the memory management and the thread system and starts an idle thread, which in turn initializes the timer management. Finally the application's main() function is called. Depending on the compiler, different methods are used to execute this function before main() is called. For ICCAVR the default crtatmega.o startup file is replaced by crtnut.o, which calls NutInit instead of main(). This is done by adding the following compiler options in the project: -ucrtnut.o nutinit.o For AVRGCC this function is located in section .init8, which is called immediately before jumping to main(). NutInit is defined as: void NutInit(void) __attribute__ ((naked)) __attribute__ ((section (".init8")));

u_long NutVersion (  void    )

Return Nut/OS version. Returns: Version coded into an unsigned long. Most significant byte is the major version number, followed by the minor version number, again followed by the release number and finally the build number in the least significant byte.

CONST char* NutVersionString (  void    )

Return Nut/OS version string. Returns: Pointer to a printable string containing the version number. The string contains 4 numbers separated by dots. The first is the major version number, followed by the minor version number, again followed by the release number and finally followed by the build number. In non-official releases this may be optionally followed by a space and an additional release state. Examples: httpd/httpserv.c, playmp3/playmp3.c, and tcps/tcps.c.
