acl_set_fd(3)							 acl_set_fd(3)

NAME
       acl_set_fd  -  Sets  the ACL on the file or directory designated by the
       file descriptor

SYNOPSIS
       #include <sys/acl.h>

       int acl_set_fd(
	       int fd,
	       acl_type_t type_d,
	       acl_t acl_d );

LIBRARY
       Security Library (libpacl.a)

PARAMETERS
       Refers to the open file descriptor of the file or directory to set  the
       ACL   on.    Designates	the  type  of  ACL  to	set:  ACL_TYPE_ACCESS,
       ACL_TYPE_DEFAULT, or ACL_TYPE_DEFAULT_DIR.   Working  storage  internal
       representation of the ACL that is being set.

DESCRIPTION
       NOTE:   This  function  is based on Draft 13 of the POSIX P1003.6 stan‐
       dard.

       Given a file descriptor to a file or directory, the acl_set_fd()	 func‐
       tion  sets  the designated ACL. The type of ACL being set is determined
       by the type_d parameter. If acl_d is NULL then the  designated  ACL  is
       removed	from  the designated file or directory. The entry pointer used
       by the acl_get_entry() function becomes undefined after a call  to  the
       acl_set_fd() function.

RETURN VALUES
       Upon  successful	 completion, the acl_set_fd() function returns a value
       of 0 (zero).  Otherwise, a value of -1 is returned and errno is set  to
       indicate the error.

ERRORS
       If  any	of  the	 following conditions occur, the acl_set_fd() function
       sets errno to the corresponding value:

       The required access to the file was denied.  The fd argument is	not  a
       valid  file  descriptor.	  The  acl_d argument does not contain a valid
       ACL. Argument type_d does not contain a valid  ACL  type	 number.   The
       directory  or  file  system  that  would	 contain the new ACL cannot be
       extended or the file system is out of file allocation  resources.   The
       argument	 type_d	 indicates  a  default ACL, and fd does not point to a
       directory.  The designated file or directory resides on a  file	system
       that  does not support ACLs.  The process does not have the appropriate
       permissions to perform the operation.  The setting and changing of ACLs
       have been disabled by the system administrator.	The designated file or
       directory resides on a read-only file system.
