NAME
       llapi_layout_stripe_countget,  llapi_layout_stripe_count_set  -	get or
       set the stripe size of a Lustre file

SYNOPSIS
       #include <lustre/lustreapi.h>

       int llapi_layout_stripe_count_get(const struct llapi_layout *layout,
					 uint64_t *stripe_count);

       int llapi_layout_stripe_count_set(struct llapi_layout *layout,
					 uint64_t stripe_count);

DESCRIPTION
       The stripe count of a Lustre file defines the number of	OSTs  used  to
       store the file.

       llapi_layout_stripe_count_get()	stores	into  stripe_count  the stripe
       count of layout.

       llapi_layout_stripe_count_get() sets the  stripe  count	of  layout  to
       stripe_count.

       A  stripe_count	value  of  LLAPI_LAYOUT_DEFAULT means that the default
       stripe count will be used.

       A stripe_count value of LLAPI_LAYOUT_WIDE means that the file  will  be
       striped as widely as possible.

RETURN VALUES
       llapi_layout_stripe_count_get()	 and   llapi_layout_stripe_count_set()
       return 0 on success, or -1 if an error occurred (in which  case,  errno
       is set appropriately).

ERRORS
       EINVAL	      An invalid argument was specified.
