acl_create_entry(3) BSD Library Functions Manual acl_create_entry(3)
NAME
acl_create_entry, acl_create_entry_np -- create a new ACL entry
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <sys/types.h>
#include <sys/acl.h>
int
acl_create_entry(acl_t *acl_p, acl_entry_t *entry_p);
int
acl_create_entry_np(acl_t *acl_p, acl_entry_t *entry_p, int entry_index);
DESCRIPTION
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.
RETURN VALUES
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.
ERRORS
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
ACL.
[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.
