/**
* Get the array of nodes which are currently blessed.
* Array indice correspond to enum IsoHfsplusBlessings.
*
* Several usage restrictions apply. See parameter blessed_nodes.
*
* @param image
* The image to inquire.
* @param blessed_nodes
* Will return a pointer to an internal node array of image.
* This pointer is valid only as long as image exists and only until
* iso_image_hfsplus_bless() gets used to manipulate the blessings.
* Do not free() this array. Do not alter the content of the array
* directly, but rather use iso_image_hfsplus_bless() and re-inquire
* by iso_image_hfsplus_get_blessed().
* This call does not impose an extra reference on the nodes in the
* array. So do not iso_node_unref() them.
* Nodes listed here are not necessarily grafted into the tree of
* the IsoImage.
* @param bless_max
* Will return the number of elements in the array.
* It is unlikely but not outruled that it will be larger than
* ISO_HFSPLUS_BLESS_MAX in this libisofs.h file.
* @param flag
* Bitfield for control purposes. Submit 0.
* @return
* 1 means success, <0 means error
*
* @since 1.2.4
