If the operation is successful zero is returned, otherwise an
appropriate error is returned.
.It Fn VOP_BLKATOFF "vp" "offset" "res" "bpp"
Return buffer
.Fa bpp
with the contents of block
.Fa offset
from the beginning of directory specified by vnode
.Fa vp .
If
.Fa res
is non-zero, fill it in with a pointer to the remaining space in the
directory.
.It Fn VOP_VALLOC "pvp" "mode" "cred" "vpp"
Allocate file system type specific data a new file in the file
system.
The argument
.Fa pvp
specifies the vnode of the directory to create the new file.
The argument
.Fa mode
specifies file system type specific flags
and
.Fa cred
are the credentials of the calling process.
The vnode of the new file is returned in the address specified by
.Fa vpp .
.It Fn VOP_BALLOC "vp" "startoffset" "size" "cred" "flags" "bpp"
Allocate the physical blocks on a device given the vnode
.Fa vp
and the offset
logical block number
.Fa startoffset
in a file.
The argument
.Fa size
specifies the size to be allocated.
The credentials of the calling processing are specified by
.Fa cred .
If the argument
.Fa bpp
is not
.Dv NULL ,
the buffer is written to the allocated blocks.
The argument
.Fa flags
is a set of flags controlling the low-level allocation when the buffer
is written.
Valid values defined in
.Aq Pa sys/buf.h
are:
.Pp
.Bl -tag -offset indent -width B_CLRBUF -compact
.It B_CLRBUF
request allocated buffer be cleared
.It B_SYNC
do all allocations synchronously
.El
.P
If the operation is successful zero is returned, otherwise an
appropriate error is returned.
.It Fn VOP_REALLOCBLKS "vp" "buflist"
Rearrange block in a file to be contiguous.
The argument
.Fa vp
is the vnode of the file to manipulate.
The argument
.Fa buflist
is a list of buffers to rearrange.
If the operation is successful zero is returned, otherwise an
appropriate error is returned.
.It Fn VOP_VFREE "pvp" "ino" "mode"
Release file resources.
This function is used by the file system to release cached file system
specific data associated with the file when the vnode is recycled.
.It Fn VOP_TRUNCATE "vp" "length" "flags" "cred" "p"
Truncate the file specified by the vnode
.Fa vp
to at most
.Fa length
size and free the unused disk blocks.
The arguments
.Fa p
and
.Fa cred
is the calling process and its credentials respectively.
The argument
.Fa flags
is a set of I/O flags.
Valid values are:
.Pp
.Bl -tag -offset indent -width IO_ALTSEMANTICS -compact
.It IO_UNIT
do I/O as atomic unit
.It IO_APPEND
append write to end
.It IO_SYNC
sync I/O file integrity completion
.It IO_NODELOCKED
underlying node already locked
.It IO_NDELAY
FNDELAY flag set in file table
.It IO_DSYNC
sync I/O data integrity completion
.It IO_ALTSEMANTICS
use alternate I/O semantics
.El
.Pp
If the operation is successful zero is returned, otherwise an
appropriate error is returned.
.It Fn VOP_UPDATE "vp" "access" "modify" "flags"
Update times on file with vnode
.Fa vp .
The access and modification times are specified by the arguments
.Fa access
and
.Fa modify
respectively.
The change time is always taken from the current time.
The argument
.Fa flags
is a set of file system type dependent flags indicating how times
should be updated:
.Pp
.Bl -tag -offset indent -width UPDATE_DIROP -compact
.It UPDATE_WAIT
wait for completion
.It UPDATE_DIROP
hint to file system to wait or not
.El
.It Fn VOP_LEASE "vp" "p" "cred" "flags"
Validate vnode credentials and operation type.
The argument
