ACL_SIZE(3)						   BSD Library Functions Manual 					       ACL_SIZE(3)

NAME

     acl_size -- get the size of the external representation of an ACL

LIBRARY

     Linux Access Control Lists library (libacl, -lacl).

SYNOPSIS

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

     ssize_t
     acl_size(acl_t acl);

DESCRIPTION

     The acl_size() function return the size, in bytes, of the buffer required to hold the exportable, contiguous, persistent form of the ACL
     pointed to by the argument acl, when converted by acl_copy_ext().

     Any existing ACL entry descriptors that refer to entries in acl continue to refer to the same entries. Any existing ACL pointers that refer
     to the ACL referred to by acl continue to refer to the ACL. The order of ACL entries within acl remains unchanged.

RETURN VALUE

     On success, the acl_size() function returns the size in bytes of the contiguous, persistent form of the ACL. On error, a value of (ssize_t)-1
     is returned and errno is set appropriately.

ERRORS

     If any of the following conditions occur, the acl_size() function returns a value of (ssize_t)-1 and sets errno to the corresponding value:

     [EINVAL]		The argument acl is not a valid pointer to an ACL.

STANDARDS

     IEEE Std 1003.1e draft 17 ("POSIX.1e", abandoned)

ACL_DELETE_ENTRY(3)					   BSD Library Functions Manual 				       ACL_DELETE_ENTRY(3)

NAME

     acl_delete_entry -- delete an ACL entry

LIBRARY

     Linux Access Control Lists library (libacl, -lacl).

SYNOPSIS

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

     int
     acl_delete_entry(acl_t acl, acl_entry_t entry_d);

DESCRIPTION

     The acl_delete_entry() function removes the ACL entry indicated by the entry_d descriptor from the ACL pointed to by acl.	Any existing ACL
     entry descriptors that refer to entries in acl other than that referred to by entry_d continue to refer to the same entries. The argument
     entry_d and any other ACL entry descriptors that refer to the same ACL entry are undefined after this function completes. Any existing ACL
     pointers that refer to the ACL referred to by acl continue to refer to the ACL.

RETURN VALUE

     The acl_delete_entry() function returns the value 0 if successful; 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, the acl_delete_entry() function returns -1 and sets errno to the corresponding value:

     [EINVAL]		The argument acl_p is not a valid pointer to an ACL.

			The argument entry_d is not a valid pointer to an ACL entry.

STANDARDS

     IEEE Std 1003.1e draft 17 ("POSIX.1e", abandoned)
