NAME

       avr_errno - <errno.h>: System Errors

   Macros
       #define EDOM   33
       #define ERANGE   34

Detailed Description

       #include <errno.h>

       Some functions in the library set the global variable errno when an error occurs. The
       file, <errno.h>, provides symbolic names for various error codes.

       Warning:
           The errno global variable is not safe to use in a threaded or multi-task system. A
           race condition can occur if a task is interrupted between the call which sets error
           and when the task examines errno. If another task changes errno during this time, the
           result will be incorrect for the interrupted task.
