grio_query_fs(3X)					     grio_query_fs(3X)

NAME    [Toc]    [Back]

     grio_query_fs - determine the bandwidth remaining on a file system

SYNOPSIS    [Toc]    [Back]

     #include <grio.h>
     int grio_query_fs(	dev_t fs_dev, int *bytes, int *seconds );

DESCRIPTION    [Toc]    [Back]

     grio_query_fs returns the amount of bandwidth available on	the file
     system specified by fs_dev.  This bandwidth is expressed as the number of
     bytes per second that the file system can provide.	This ratio can be used
     as	a quick	check to determine if the desired bandwidth will be available
     from a given file system, before calling grio_reserve_file(3X) or
     grio_reserve_fs(3X).  The ggd daemon is queried about the remaining file
     system bandwidth.

DIAGNOSTICS    [Toc]    [Back]

     On	success, a zero	is returned and	the bytes and seconds fields contain a
     ratio indicating the available bandwidth.	EIO is returned	if the
     bandwidth of the file system specified by fs_dev cannot be	determined.
