ACL_INIT(3)                             BSD Library Functions Manual                             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.

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.
