ACL_SET(3)		 BSD Library Functions Manual		    ACL_SET(3)

NAME
     acl_set_fd, acl_set_fd_np, acl_set_file, acl_set_link_np — set an ACL for
     a file

LIBRARY
     Standard C Library (libc, -lc)

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

     int
     acl_set_fd(int fd, acl_t acl);

     int
     acl_set_fd_np(int fd, acl_t acl, acl_type_t type);

     int
     acl_set_file(const char *path_p, acl_type_t type, acl_t acl);

     int
     acl_set_link_np(const char *path_p, acl_type_t type, acl_t acl);

DESCRIPTION
     The acl_set_fd(), acl_set_fd_np(), acl_set_file(), and acl_set_link_np()
     each associate an ACL with an object referred to by fd or path_p.	The
     acl_set_fd_np() and acl_set_link_np() functions are not POSIX.1e calls.
     The acl_set_fd() function allows only the setting of ACLs of type
     ACL_TYPE_ACCESS where as acl_set_fd_np() allows the setting of ACLs of
     any type.	The acl_set_link_np() function acts on a symlink rather than
     its target, if the target of the path is a symlink.

     Valid values for the type argument are:

	ACL_TYPE_ACCESS	    POSIX.1e access ACL
	ACL_TYPE_DEFAULT    POSIX.1e default ACL
	ACL_TYPE_NFS4	    NFSv4 ACL

     Trying to set ACL_TYPE_NFS4 with acl branded as POSIX.1e, or
     ACL_TYPE_ACCESS or ACL_TYPE_DEFAULT with ACL branded as NFSv4, will
     result in error.

IMPLEMENTATION NOTES
     FreeBSD's support for POSIX.1e interfaces and features is still under
     development at this time.

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]		Argument acl does not point to a valid ACL for this
			object, or the ACL type specified in type is invalid
			for this object, or there is branding mismatch.

     [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 argu‐
			ment points to an empty string.

     [ENOMEM]		Insufficient memory available to fulfill request.

     [ENOSPC]		The directory or file system that would contain the
			new ACL cannot be extended, or the file system is out
			of file allocation resources.

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

     [EROFS]		This function requires modification of a file system
			which is currently read-only.

STANDARDS
     POSIX.1e is described in IEEE POSIX.1e draft 17.  Discussion of the draft
     continues on the cross-platform POSIX.1e implementation mailing list.  To
     join this list, see the FreeBSD POSIX.1e implementation page for more
     information.

HISTORY
     POSIX.1e support was introduced in FreeBSD 4.0, and development contin‐
     ues.
