ACL_ADD_FLAG_NP(3)					   BSD Library Functions Manual 					ACL_ADD_FLAG_NP(3)

NAME
     acl_add_flag_np -- add flags to a flagset

LIBRARY
     Standard C Library (libc, -lc)

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

     int
     acl_add_flag_np(acl_flagset_t flagset_d, acl_flag_t flag);

DESCRIPTION
     The acl_add_flag_np() function is a non-portable call that adds the NFSv4 ACL flags contained in flags to the flagset flagset_d.

     Note: it is not considered an error to attempt to add flags that already exist in the flagset.

     Valid values are:

	ACL_ENTRY_FILE_INHERIT		  Will be inherited by files.
	ACL_ENTRY_DIRECTORY_INHERIT	  Will be inherited by directories.
	ACL_ENTRY_NO_PROPAGATE_INHERIT	  Will not propagate.
	ACL_ENTRY_INHERIT_ONLY		  Inherit-only.

RETURN VALUES
     The acl_add_flag_np() 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
     The acl_add_flag_np() function fails if:

     [EINVAL]		Argument flagset_d is not a valid descriptor for a flagset within an ACL entry.  Argument flag does not contain a valid
			acl_flag_t value.
