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 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 acl_create_entry_np() function is a non-portable version that creates the ACL entry at position index. Positions are numbered starting from zero, i.e. calling acl_create_entry_np() with index argument equal to zero will prepend the entry to the ACL.

RETURN VALUES

The acl_create_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

The acl_create_entry() function fails if:

[EINVAL]: Argument acl_p does not point to a pointer to a valid ACL. Argument index is out of bounds.
[ENOMEM]: The ACL working storage requires more memory than is allowed by the hardware or system-imposed memory management constraints.

STANDARDS

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

HISTORY

POSIX.1e support was introduced in FreeBSD 4.0. The acl_create_entry() function was added in FreeBSD 5.0.
