.Sh DESCRIPTION
The
.Fn libvhdi_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 "libvhdi.h".
.Sh ENVIRONMENT
None
.Sh FILES
None
.Sh NOTES
libvhdi allows to be compiled with wide character support (wchar_t).

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

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