acl_get_entry(3)					      acl_get_entry(3)

NAME
       acl_get_entry - Returns a descriptor to an ACL entry

SYNOPSIS
       #include <sys/acl.h>

       acl_entry_t acl_get_entry(
	       acl_t acl_d );

LIBRARY
       Security Library (libpacl.a)

PARAMETERS
       Specifies the working storage internal representation ACL descriptor.

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

       The acl_get_entry() function returns a pointer to the next entry in the
       specified ACL.

       Following  a call to the acl_get_fd(), acl_get_file(), acl_from_text(),
       or acl_first_entry() function, the first call  to  the  acl_get_entry()
       function	 obtains  the  first entry in the ACL. Subsequent calls obtain
       successive entries in the ACL, until the last entry is obtained.	 After
       the last entry has been obtained, the value 0 (zero) is returned.

RETURN VALUES
       Upon  successful	 completion,  the  acl_get_entry()  function returns a
       pointer to the ACL entry descriptor. If the last ACL has	 already  been
       returned	 by  a	previous  call to this function, or the ACL has no ACL
       entries, the function returns a value of 0 (zero).  Otherwise, a	 value
       of NULL is returned and errno is set to indicate the error.

ERRORS
       The acl_d parameter does not refer to a valid ACL structure.  The posi‐
       tion of the ACL entry must be reset using the acl_first_entry() library
       routine.
