DIRECTION

client OS filesystem library

DESCRIPTION

This method returns the attributes of this filesystem. out_stats is a pointer to an oskit_statfs_t structure defined as follows:

struct oskit_statfs  {

	    oskit_u32_t bsize;   /* file system block size */
	    oskit_u32_t frsize;  /* fundamental file system block size */
	    oskit_u32_t blocks;  /* total blocks in fs in units of frsize */
	    oskit_u32_t bfree;   /* free blocks in fs */
	    oskit_u32_t bavail;  /* free blocks avail to non-superuser */
	    oskit_u32_t files;   /* total file nodes in file system */
	    oskit_u32_t ffree;   /* free file nodes in fs */
	    oskit_u32_t favail;  /* free file nodes avail to non-superuser */
	    oskit_u32_t fsid;    /* file system id */
	    oskit_u32_t flag;    /* mount flags */	
	    oskit_u32_t namemax; /* max bytes in a file name */
	 

};
