.Sh DESCRIPTION
The
.Fn libsmdev_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 "libsmdev.h".
.Sh ENVIRONMENT
None
.Sh FILES
None
.Sh NOTES
libsmdev allows to be compiled with wide character support (wchar_t).
To compile libsmdev with wide character support use:
.Ar ./configure --enable-wide-character-type=yes
or define:
.Ar _UNICODE
or
.Ar UNICODE
during compilation.
.Ar LIBSMDEV_WIDE_CHARACTER_TYPE
in libsmdev/features.h can be used to determine if libsmdev was compiled with wide character support.
