I was considering this, but in the VIR_STORAGE_VOL_LAST value defined
virStorageVolType enum is protected by an ifdef:
typedef enum {
VIR_STORAGE_VOL_FILE = 0, /* Regular file based volumes */
VIR_STORAGE_VOL_BLOCK = 1, /* Block based volumes */
VIR_STORAGE_VOL_DIR = 2, /* Directory-passthrough based volume */
VIR_STORAGE_VOL_NETWORK = 3,/* Network volumes like RBD (RADOS
Block Device) */
#ifdef VIR_ENUM_SENTINELS
VIR_STORAGE_VOL_LAST <- here
#endif
} virStorageVolType;
As I don't know what are the conditions that make VIR_ENUM_SENTINELS
defined I didn't want to risk a broken build.
