ACL_INIT(3) BSD Library Functions Manual ACL_INIT(3)NAMEacl_init — initialize ACL working storage
LIBRARY
library “libposix1e”
SYNOPSIS
#include <sys/types.h>
#include <sys/acl.h>
acl_t
acl_init(int count);
DESCRIPTION
The acl_init() function allocates and initializes the working storage for
an ACL of at least count ACL entries. A pointer to the working storage
is returned. The working storage allocated to contain the ACL is freed
by a call to acl_free(3). When the area is first allocated, it shall
contain an ACL that contains no ACL entries.
This function may cause memory to be allocated. The caller should free
any releasable memory, when the new ACL is no longer required, by calling
acl_free(3) with the (void*)acl_t as an argument.
IMPLEMENTATION NOTES
DragonFly's support for POSIX.1e interfaces and features is still under
development at this time.
RETURN VALUES
Upon successful completion, this function shall return a pointer to the
working storage. Otherwise, a value of (acl_t)NULL shall be returned,
and errno shall be set to indicate the error.
ERRORS
If any of the following conditions occur, the acl_init() function shall
return a value of (acl_t)NULL and set errno to the corresponding value:
[EINVAL] The value of count is less than zero.
[ENOMEM] The acl_t to be returned requires more memory than is
allowed by the hardware or system-imposed memory man‐
agement constraints.

POSIX.1e is described in IEEE POSIX.1e draft 17. Discussion of the draft
continues on the cross-platform POSIX.1e implementation mailing list. To
join this list, see the FreeBSD POSIX.1e implementation page for more
information.
HISTORY
POSIX.1e support was introduced in FreeBSD 4.0, and development contin‐
ues.

BUGS
These features are not yet fully implemented. In particular, the shipped
version of UFS/FFS does not support storage of additional security
labels, and so is unable to (easily) provide support for most of these
features.
