getacl

getacl(2)							System Calls Manual							 getacl(2)

NAME

       getacl, fgetacl - get access control list (ACL) information (HFS File Systems only)

SYNOPSIS

DESCRIPTION

       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.
