acl_init: initialize ACL working storage

NAME

acl_init - initialize ACL working storage

LIBRARY

Linux Access Control Lists library (libacl, -lacl).

SYNOPSIS

In sys/types.h In sys/acl.h Ft acl_t Fn acl_init int count

DESCRIPTION

The Fn acl_init function allocates and initializes the working storage for an ACL of at least count ACL entries. The ACL created initially contains no ACL entries. A pointer to the working storage is returned.

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_free3 with the (void*)acl_t returned by Fn acl_init as an argument.

RETURN VALUE

On success, this function returns a pointer to the working storage. On error, a value of (acl_t)NULL is returned, and errno is set appropriately.

ERRORS

If any of the following conditions occur, the Fn acl_init function returns a value of (acl_t)NULL and sets errno to the corresponding value:

Bq Er EINVAL

The value of count is less than zero.

Bq Er ENOMEM

The acl_t to be returned requires more memory than is allowed by the hardware or system-imposed memory management constraints.

STANDARDS

IEEE Std 1003.1e draft 17 ("POSIX.1e", abandoned)
