SYNOPSIS

9       int     lsm_local_disk_link_type_get     (const     char    *disk_path,
10       lsm_disk_link_type *link_type, lsm_error **lsm_err);

ARGUMENTS

13       disk_path   String. The path of disk, example "/dev/sdb".:
14
15       link_type   Output pointer of lsm_disk_link_type.
16
17       lsm_err     Output pointer of lsm_error. Error message  could  be:  re‐
18                   trieved  via  lsm_error_message_get. Memory should be freed
19                   by lsm_error_free.
