DESCRIPTION
     The libcreg_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 "libcreg.h".

ENVIRONMENT
     None

FILES
     None

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

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

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