The facility allows the client to perform pathname translation
and lookup operations. The functions will increment the refer‐
ence count for the vnode in question. The reference count has to
be decremented after use of the vnode, by using either or depend‐
ing on whether the flag was specified or not. The function is
used to initialize components. It takes the following arguments:
The to initialize. The operation which will perform. The fol‐
lowing operations are valid: and The latter three are just setup
for those effects; just calling will not result in being called.
Operation flags. Several of these can be effective at the same
time. UIO segment indicator. This indicates if the name of the
object is in userspace or in the kernel address space Pointer to
the component's pathname buffer (the file or directory name that
will be looked up). The thread context to use for operations and
locks. The function takes the following set of that influence
its operation: Lock vnode on return with unless is also set. The
should be used to release the lock (or which is equivalent to
calling followed by all in one). This flag lets the function re‐
turn the parent (directory) vnode, in locked state, unless it is
identical to in which case is not locked per se (but may be
locked due to If a lock is enforced, it should be released using
or and Lock vnode on return with The should be used to release
the lock (or which is equivalent to calling followed by all in
one). This flag allows the function to return the parent (direc‐
tory) vnode in an unlocked state. The parent vnode must be re‐
leased separately by using Avoid creating this entry in the name‐
cache if it is not already present. Normally, will add entries
to the name cache if they are not already there. With this flag,
will follow the symbolic link if the last part of the path sup‐
plied is a symbolic link (i.e., it will return a vnode for what‐
ever the link points at, instead for the link itself). Do not
follow symbolic links (pseudo). This flag is not looked for by
the actual code, which looks for is used to indicate to the
source code reader that symlinks are intentionally not followed.
Do not free the pathname buffer at the end of the invocation; in‐
stead, free it later in so that the caller may access the path‐
name buffer. See below for details. Retain an additional refer‐
ence to the parent directory; do not free the pathname buffer.
See below for details. The structure is composed of the follow‐
ing fields: In the normal case, this is either the current direc‐
tory or the root. It is the current directory if the name passed
in does not start with and we have not gone through any symlinks
with an absolute path, and the root otherwise. In this case, it
is only used by and should not be considered valid after a call
to If is set, this is set to the same as with an extra To block
from releasing the can be set. Vnode pointer to directory of the
object on which lookup is performed. This is available on suc‐
cessful return if or is set. It is locked if is set. Freeing
this in can be inhibited by or (with the obvious effects). Vnode
pointer to the resulting object, otherwise. The field of this
vnode is incremented. If is set, it is also locked. Freeing
this in can be inhibited by or (with the obvious effects). The
pathname buffer contains the location of the file or directory
that will be used by the operations. It is managed by the zone
allocation interface. If the or flag is set, then the pathname
buffer is available after calling the function. To only deallo‐
cate resources used by the pathname buffer, then flag can be
passed to the function. To keep the pathname buffer intact, the
flag can be passed to the function. If successful, will return
0, otherwise it will return an error. Errors which may return: A
component of the specified pathname is not a directory when a di‐
rectory is expected. A component of a pathname exceeded 255
characters, or an entire pathname exceeded 1023 characters. A
component of the specified pathname does not exist, or the path‐
name is an empty string. An attempt is made to access a file in
a way forbidden by its file access permissions. Too many sym‐
bolic links were encountered in translating the pathname. An at‐
tempt is made to open a directory with write mode specified. The
last component of the pathname specified for a or operation is An
attempt is made to modify a file or directory on a read-only file
system. This manual page was written by and later significantly
revised by The flag does not always result in the parent vnode
being locked. This results in complications when the is used.
In order to solve this for the cases where both and are used, it
is necessary to resort to recursive locking.
