grio_query_fs(3X)					     grio_query_fs(3X)

NAME
     grio_query_fs - determine the bandwidth remaining on a file system

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

DESCRIPTION
     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
     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.

FILES
     /etc/grio_disks

NOTE
     The guaranteed rate I/O capabilities described in this man page refer to
     the version one GRIO implementation. Refer to grio2(5) for information
     covering the newer GRIO Version 2 implementation which supports both
     local and clustered XVM volumes.
