DESCRIPTION

The libbfio_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 "libbfio.h".

ENVIRONMENT

None

FILES

None

NOTES

libbfio allows to be compiled with wide character support (wchar_t).

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

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