/**
* gdk_pixmap_create_from_xpm_d:
* @drawable: a #GdkDrawable, used to determine default values
* for the new pixmap.
* @mask: (out): Pointer to a place to store a bitmap representing
* the transparency mask of the XPM file. Can be %NULL,
* in which case transparency will be ignored.
* @transparent_color: This color will be used for the pixels
* that are transparent in the input file. Can be %NULL
* in which case a default color will be used.
* @data: Pointer to a string containing the XPM data.
*
* Create a pixmap from data in XPM format.
*
* Returns: (transfer none): the #GdkPixmap.
*
* Deprecated: 2.22: Use a #GdkPixbuf instead. You can use
* gdk_pixbuf_new_from_xpm_data() to create it.
* If you must use a pixmap, use gdk_pixmap_new() to
* create it and Cairo to draw the pixbuf onto it.
