SYNOPSIS

9       int  lsm_local_disk_link_speed_get  (const  char  *disk_path,  uint32_t
10       *link_speed, lsm_error **lsm_err);
11

ARGUMENTS

13       disk_path   String. The path  of  block  device,  example:  "/dev/sdb",
14                   "/dev/nvme0n1".
15
16       link_speed  Output pointer of link speed in Mbps.
17
18       lsm_err     Output   pointer  of  lsm_error.  Error  message  could  be
19                   retrieved via lsm_error_message_get. Memory should be freed
20                   by lsm_error_free.

DESCRIPTION

23       1.4
24
25       Query  the  current negotiated disk link speed.  Requires permission to
26       open disk path(root user or disk group).  The output speed is in  Mbps.
27       For     example,     3.0     Gbps    will    get    3000.     Set    to
28       0(LSM_DISK_LINK_SPEED_UNKNOWN) if error.
