VRTSvxfs
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.
