getvfsstat
() returns information about all mounted file
systems. buf is a pointer to an array of
statvfs
structures defined in
statvfs(5).
The buffer is filled with an array of statvfs structures, one for each mounted file system up to the size specified by bufsize.
If buf is given as
NULL
, getvfsstat
() returns
just the number of mounted file systems.
Normally flags should be specified as
ST_WAIT
. If flags is set to
ST_NOWAIT
, getvfsstat
() will
return the information it has available without requesting an update from
each file system. Thus, some of the information will be out of date, but
getvfsstat
() will not block waiting for information
from a file system that is unable to respond.
getvfsstat
() fails if one or more of the following are
true:
getvfsstat
() function first appeared in
NetBSD 3.0 to replace
getfsstat
() which appeared in
4.4BSD.
