DESCRIPTION
     The libsmdev_get_version() function is used to retrieve the library
     version.

RETURN VALUES
     Most of the functions return NULL or -1 on error, dependent on the return
     type.  For the actual return values see "libsmdev.h".

ENVIRONMENT
     None

FILES
     None libsmdev allows to be compiled with wide character support
     (wchar_t).

     To compile libsmdev with wide character support use: ./configure
     --enable-wide-character-type=yes
      or define: _UNICODE
      or UNICODE
      during compilation.

     LIBSMDEV_WIDE_CHARACTER_TYPE
      in libsmdev/features.h can be used to determine if libsmdev was compiled
     with wide character support.
