DESCRIPTION

The Fn libqcow_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 "libqcow.h".

ENVIRONMENT

None

FILES

None libqcow allows to be compiled with wide character support (wchar_t).

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

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