ACL_CREATE_ENTRY(3)	 BSD Library Functions Manual	   ACL_CREATE_ENTRY(3)

     acl_create_entry, acl_create_entry_np — create a new ACL entry

     Standard C Library (libc, -lc)

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

     acl_create_entry(acl_t *acl_p, acl_entry_t *entry_p);

     acl_create_entry_np(acl_t *acl_p, acl_entry_t *entry_p, int entry_index);

     The acl_create_entry() function is a POSIX.1e call that creates a new ACL
     entry in the ACL pointed to by acl_p.  The function will return in
     entry_p a descriptor for this ACL entry.

     The acl_create_entry_np() function is a non-portable extension which
     allows the caller to specify the position of the created entry within the
     ACL.  If entry_index is ACL_FIRST_ENTRY the entry will be created at the
     head of the ACL.  If entry_index is ACL_LAST_ENTRY the entry will be cre‐
     ated at the end of the ACL.  After inserting an ACL entry with an
     entry_index other than ACL_LAST_ENTRY the behaviour of any acl_entry_t's
     previously obtained from the ACL by acl_create_entry() or acl_get_entry()
     is undefined.

     The acl_create_entry() function returns the value 0 if successful; other‐
     wise the value -1 is returned and the global variable errno is set to
     indicate the error.

     The acl_create_entry() and acl_create_entry_np() functions fail if:

     [EINVAL]		Argument acl_p does not point to a pointer to a valid

     [ENOMEM]		The ACL working storage requires more memory than is
			allowed by the hardware or system-imposed memory man‐
			agement constraints.

     [ERANGE]		The entry_index argument to acl_create_entry_np() is
			greater than the number of entries in the ACL.

     acl(3), acl_delete_entry(3), acl_get_entry(3), posix1e(3)

     POSIX.1e is described in IEEE POSIX.1e draft 17.
