.Sh DESCRIPTION
The
.Fn libregf_get_version
function is used to retrieve the library version.
.Sh RETURN VALUES
Most of the functions return NULL or \-1 on error, dependent on the return type.
For the actual return values see "libregf.h".
.Sh ENVIRONMENT
None
.Sh FILES
None
.Sh NOTES
libregf allows to be compiled with wide character support (wchar_t).

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

.Ar LIBREGF_WIDE_CHARACTER_TYPE
 in libregf/features.h can be used to determine if libregf was compiled with wide character support.
