DCMD_F3S_GETCMP

Get the compresssion setting for a flash filesystem

Synopsis:

#include <sys/dcmd_f3s.h>

#define DCMD_F3S_GETCMP    __DIOTF(_DCMD_F3S, F3S_GETCMP, f3s_cmdcmp_t)

Argument	Value
`filedes`	A file descriptor that you obtained by opening the device.
`dcmd`	DCMD_F3S_GETCMP
`dev_data_ptr`	A pointer to a f3s_cmdcmp_t structure (see below)
`n_bytes`	`sizeof(f3s_cmdcmp_t)`
`dev_info_ptr`	NULL

This command gets the compression setting for a flash filesystem.

A f3s_cmdcmp_t structure:

typedef struct f3s_cmdcmp_s
{
  uint32_t status;    /* cmdcmp status */
  uint32_t cmp_flag;  /* compression flag */
}
f3s_cmdcmp_t;

If cmd_flag is nonzero, the filesystem is compressed.
