DESCRIPTION

       The libluksde_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 "libluksde.h".

ENVIRONMENT

       None

FILES

       None

NOTES

       libluksde can be compiled with wide character support (wchar_t).

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

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