DCMD_F3S_PARTINFO

Get information about a partition

Synopsis:

#include <sys/dcmd_f3s.h>

#define DCMD_F3S_PARTINFO  __DIOTF(_DCMD_F3S, F3S_PARTINFO, f3s_partinfo_t)

Arguments to devctl():

Argument Value
filedes A file descriptor that you obtained by opening the device.
dcmd DCMD_F3S_PARTINFO
dev_data_ptr A pointer to a f3s_partinfo_t structure (see below)
n_bytes sizeof(f3s_partinfo_t)
dev_info_ptr NULL

Description:

This command gets information about a partition.

Input:

None.

Output:

A f3s_partinfo_t structure, filled in by the driver: 

typedef struct f3s_partinfo_s
{
  uint32_t status;       /* info status */
  uint32_t total_size;   /* total size of partition expressed in bytes */
  uint32_t unit_size;    /* size of a unit expressed in bytes */
  uint32_t spare_size;   /* spare size within partition expressed in bytes */
  uint32_t retire_size;  /* retired size within partition expressed in bytes */
  uint32_t head_size;    /* overhead size expressed in bytes */
  uint32_t pad_size;     /* alignment padding size expressed in bytes */
  uint32_t free_size;    /* free size in partition expressed in bytes */
  uint32_t stale_size;   /* stale size in partition expressed in bytes */
  uint32_t resv_size;    /* reserved size in partition expressed in bytes */
}
f3s_partinfo_t;
