/**
* gdk_property_get:
* @window: a #GdkWindow.
* @property: the property to retrieve.
* @type: the desired property type, or %GDK_NONE, if any type of data
* is acceptable. If this does not match the actual
* type, then @actual_format and @actual_length will
* be filled in, a warning will be printed to stderr
* and no data will be returned.
* @offset: the offset into the property at which to begin
* retrieving data, in 4 byte units.
* @length: the length of the data to retrieve in bytes. Data is
* considered to be retrieved in 4 byte chunks, so @length
* will be rounded up to the next highest 4 byte boundary
* (so be careful not to pass a value that might overflow
* when rounded up).
* @pdelete: if %TRUE, delete the property after retrieving the
* data.
* @actual_property_type: location to store the actual type of
* the property.
* @actual_format: location to store the actual return format of the
* data; either 8, 16 or 32 bits.
* @actual_length: location to store the length of the retrieved data, in
* bytes. Data returned in the 32 bit format is stored
* in a long variable, so the actual number of 32 bit
* elements should be be calculated via
* @actual_length / sizeof(glong) to ensure portability to
* 64 bit systems.
* @data: location to store a pointer to the data. The retrieved
* data should be freed with g_free() when you are finished
* using it.
*
* Retrieves a portion of the contents of a property. If the
* property does not exist, then the function returns %FALSE,
* and %GDK_NONE will be stored in @actual_property_type.
*
* <note>
* <para>
* The XGetWindowProperty() function that gdk_property_get()
* uses has a very confusing and complicated set of semantics.
* Unfortunately, gdk_property_get() makes the situation
* worse instead of better (the semantics should be considered
* undefined), and also prints warnings to stderr in cases where it
* should return a useful error to the program. You are advised to use
* XGetWindowProperty() directly until a replacement function for
* gdk_property_get()
* is provided.
* </para>
* </note>
*
* Returns: %TRUE if data was successfully received and stored
* in @data, otherwise %FALSE.
