DESCRIPTION
The libvshadow_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 "libvshadow.h".

ENVIRONMENT
None

FILES
None libvshadow allows to 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 compiled with wide character support.
