Description

Variables and functions to check the libxfce4windowing version.

Functions

LIBXFCE4WINDOWING_CHECK_VERSION()

#define             LIBXFCE4WINDOWING_CHECK_VERSION(major, minor, micro)

A macro to compare libxfce4windowing versions to determine if a particular function is available.

Parameters

major	The major version of the library, i.e. 4
minor	The minor version of the library, i.e. 18
micro	The micro release of the library, i.e. 0

libxfce4windowing_check_version ()

const gchar *
libxfce4windowing_check_version (guint required_major,
                                 guint required_minor,
                                 guint required_micro);

Checks that the libxfce4windowing library in use is compatible with the given version. Generally you would pass in the constants LIBXFCE4WINDOWING_MAJOR_VERSION, LIBXFCE4WINDOWING_MINOR_VERSION and LIBXFCE4WINDOWING_MICRO_VERSION as the three arguments to this function; that produces a check that the library in use is compatible with the version of libxfce4windowing the extension was compiled against.

const gchar *mismatch;
mismatch = libxfce4windowing_check_version(LIBXFCE4WINDOWING_MAJOR_VERSION,
                                           LIBXFCE4WINDOWING_MINOR_VERSION,
                                           LIBXFCE4WINDOWING_MICRO_VERSION);
if (G_UNLIKELY(mismatch != NULL)) {
  g_error("Version mismatch: %s", mismatch);
}

Parameters

required_major	the required major version.
required_minor	the required minor version.
required_micro	the required micro version.

Returns

NULL if the library is compatible with the given version, or a string describing the version mismatch. The returned string is owned by the library and must not be freed or modified by the caller.
