vxfs_vol_enumerate() fills in the array of fsdev_info structures with information on the component volumes in a file system.

The file descriptor fd must be the mount point of the file system. Upon entry, *countp must contain the number of structures in the array pointed to by infop. On return, *countp is updated with the number of records that were filled in. If the error E2BIG is returned, *countp contains the minimum number of records necessary for the call to succeed.

vxfs_vol_enumerate() returns zero on success, non-zero on failure.

E2BIG	The amount of data to return is too large to fit in the specified array.
EINVAL	The number of structures specified by fname is not correct.
ENOENT	The specified array does not exist.
ENOMEM	Memory could not be allocated to support the API.
ENOTSUP	This operation is not supported by the disk layout version of the specified file system. Use vxupgrade(1m) to enable this operation.
ERANGE	The result was too large.
