DESCRIPTION

The () 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 "libfvde.h".

ENVIRONMENT

None

FILES

None

NOTES

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

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

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