getacl(2)getacl(2)NAME
getacl, fgetacl - get access control list (ACL) information (HFS File
Systems only)
SYNOPSISDESCRIPTION
returns a complete listing of all ACL entries (uid.gid, mode) in an
existing file's access control list. path points to a path name of a
file.
Similarly, returns a complete listing of all ACL entries for an open
file known by the file descriptor fildes.
nentries is the number of entries being reported on, and is never more
than the constant defined in If nentries is non-zero, it must be at
least as large as the number of entries in the file's ACL, including
base entries (see setacl(2)). returns the number of entries in the
file's ACL, as well as the ACL entries themselves in the array of
structures acl declared by the calling program.
If nentries is zero, returns the number of entries in the file's ACL,
including base ACL entries, and acl is ignored.
Entries are reported in groups of decreasing order of specificity (see
setacl(2)), then sorted in each group by user ID and group ID. The
content of array entries beyond the number of defined entries for the
file is undefined.
RETURN VALUE
Upon successful completion, and return a non-negative value. If an
error occurs, a value of −1 is returned, and is set to indicate the
error.
ERRORS
fails to modify the acl array if any of the following is true:
A component of the
path prefix is not a directory.
The named file does not exist (for example,
path is null or a component of path does not
exist).
A component of the
path prefix denies search permission.
path or a portion of acl to be written points outside
the allocated address space of the process.
nentries is non-zero and less than the number of entries
in the file's ACL, or it is greater than
is not supported on remote files by some networking services.
The function is not supported by this file system type.
The system file table is full.
The length of path exceeds bytes, or the length of a component
of path exceeds bytes while is in effect.
Too many symbolic links were encountered in translating the
path name.
fails to modify the acl array if any of the following is true:
fildes is not a valid file descriptor.
nentries is non-zero and less than the number of entries
in the file's ACL, or it is greater than
The function is not supported by this file system type.
The system file table is full.
EXAMPLES
The following call returns the number of entries in the ACL on file
The following call returns in acl all entries in the ACL on the file
opened with file descriptor 5.
DEPENDENCIES
and are only supported on HFS file system on standard HP-UX operating
system.
