LIBRARY


.Lb libc

SYNOPSIS


.In sys/types.h
.In 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


.Fx Ns ’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 management constraints.

STANDARDS

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
.Fx POSIX.1e implementation page for more information.

HISTORY

POSIX.1e support was introduced in
.Fx 4.0 , and development continues.
