Functions

Types and Values

Includes

#include <libxfce4windowingui/libxfce4windowingui.h>

Description

Variables and functions to check the libxfce4windowingui version.

Functions

LIBXFCE4WINDOWINGUI_CHECK_VERSION()

#define             LIBXFCE4WINDOWINGUI_CHECK_VERSION(major, minor, micro)

A macro to compare libxfce4windowingui 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

 

libxfce4windowingui_check_version ()

const gchar *
libxfce4windowingui_check_version (guint required_major,
                                   guint required_minor,
                                   guint required_micro);

Checks that the libxfce4windowingui library in use is compatible with the given version. Generally you would pass in the constants LIBXFCE4WINDOWINGUI_MAJOR_VERSION, LIBXFCE4WINDOWINGUI_MINOR_VERSION and LIBXFCE4WINDOWINGUI_MICRO_VERSION as the three arguments to this function; that produces a check that the library in use is compatible with the version of libxfce4windowingui the extension was compiled against.

const gchar *mismatch;
mismatch = libxfce4windowingui_check_version(LIBXFCE4WINDOWINGUI_MAJOR_VERSION,
                                             LIBXFCE4WINDOWINGUI_MINOR_VERSION,
                                             LIBXFCE4WINDOWINGUI_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.
