ACL_DELETE

NAME
     acl_delete_fd_np, acl_delete_file_np acl_delete_link_np -- delete an ACL
     from a file

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <sys/types.h>
     #include <sys/acl.h>

     int
     acl_delete_fd_np(int filedes, acl_type_t type);

     int
     acl_delete_file_np(const char *path_p, acl_type_t type);

     int
     acl_delete_link_np(const char *path_p, acl_type_t type);

DESCRIPTION
     The acl_delete_fd_np(), acl_delete_file_np(), and acl_delete_link_np()
     each allow the deletion of an ACL from a file.  These functions are nonportable
     extensions that permit the deletion of arbitrary ACL types from
     a file/directory either by path name or file descriptor.  The _file()
     variations follow a symlink if it occurs in the last segment of the path
     name; the _link() variations operate on the symlink itself.

RETURN VALUES
     Upon successful completion, the value 0 is returned; otherwise the
     value -1 is returned and the global variable errno is set to indicate the
     error.

ERRORS
     If any of the following conditions occur, these functions shall return -1
     and set errno to the corresponding value:

     [EACCES]           Search permission is denied for a component of the
                        path prefix, or the object exists and the process does
                        not have appropriate access rights.

     [EBADF]            The fd argument is not a valid file descriptor.

     [EINVAL]           The ACL type passed is invalid for this file object.

     [ENAMETOOLONG]     A component of a pathname exceeded 255 characters, or
                        an entire path name exceeded 1023 characters.

     [ENOENT]           The named object does not exist, or the path_p argument
                        points to an empty string.

     [ENOMEM]           Insufficient memory available to fulfill request.

     [ENOTDIR]          A component of the path prefix is not a directory.

                        Argument path_p must be a directory, and is not.

     [EOPNOTSUPP]       The file system does not support ACL deletion.

     [EPERM]            The process does not have appropriate privilege to
                        perform the operation to delete an ACL.

     [EROFS]            The file system is read-only.
