       avr_version - <avr/version.h>: avr-libc version macros

SYNOPSIS

   Macros
       #define __AVR_LIBC_VERSION_STRING__   '2.0.0'
       #define __AVR_LIBC_VERSION__   20000UL
       #define __AVR_LIBC_DATE_STRING__   '20150208'
       #define __AVR_LIBC_DATE_   20150208UL
       #define __AVR_LIBC_MAJOR__   2
       #define __AVR_LIBC_MINOR__   0
       #define __AVR_LIBC_REVISION__   0

Detailed Description

       #include <avr/version.h>

       This header file defines macros that contain version numbers and strings describing the current version
       of avr-libc.

       The version number itself basically consists of three pieces that are separated by a dot: the major
       number, the minor number, and the revision number. For development versions (which use an odd minor
       number), the string representation additionally gets the date code (YYYYMMDD) appended.

       This file will also be included by <avr/io.h>. That way, portable tests can be implemented using
       <avr/io.h> that can be used in code that wants to remain backwards-compatible to library versions prior
       to the date when the library version API had been added, as referenced but undefined C preprocessor
       macros automatically evaluate to 0.

Macro Definition Documentation

   #define __AVR_LIBC_DATE_   20150208UL
       Numerical representation of the release date.

   #define __AVR_LIBC_DATE_STRING__   '20150208'
       String literal representation of the release date.

   #define __AVR_LIBC_MAJOR__   2
       Library major version number.

   #define __AVR_LIBC_MINOR__   0
       Library minor version number.

   #define __AVR_LIBC_REVISION__   0
       Library revision number.

   #define __AVR_LIBC_VERSION__   20000UL
       Numerical representation of the current library version.

       In the numerical representation, the major number is multiplied by 10000, the minor number by 100, and
       all three parts are then added. It is intented to provide a monotonically increasing numerical value that
       can easily be used in numerical checks.

   #define __AVR_LIBC_VERSION_STRING__   '2.0.0'
       String literal representation of the current library version.
