ACL_ENTRIES(3)						   BSD Library Functions Manual 					    ACL_ENTRIES(3)

NAME

     acl_entries -- return the number of entries in an ACL

LIBRARY

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

SYNOPSIS

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

     int
     acl_entries(acl_t acl);

DESCRIPTION

     The acl_entries() function returns the number of ACL entries that are contained in the ACL referred to by the argument acl.

RETURN VALUE

     The acl_entries() function returns the number of entries in acl 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_entries() function returns -1 and sets errno to the corresponding value:

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

STANDARDS

     This is a non-portable, Linux specific extension to the ACL manipulation functions defined in IEEE Std 1003.1e draft 17 ("POSIX.1e", aban-
     doned).

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)
