acl_init(3)

NAME

     acl_init -- initialize ACL working storage

LIBRARY

     Standard C Library (libc, -lc)

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

     FreeBSD'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.

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 FreeBSD POSIX.1e implementation page for more
     information.

HISTORY

     POSIX.1e support was introduced in FreeBSD 4.0, and development contin-
     ues.
