DESCRIPTION
     The libvshadow_get_version() function is used to retrieve the library  ver-
     sion.

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

ENVIRONMENT
     None

FILES
     None

NOTES
     libvshadow can be compiled with wide character support (wchar_t).

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

     LIBVSHADOW_WIDE_CHARACTER_TYPE
      in  libvshadow/features.h  can be used to determine if libvshadow was com-
     piled with wide character support.
