NAME

     acl_copy_int — copy an ACL from external to internal representation

LIBRARY

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

SYNOPSIS

     #include <sys/types.h>
     #include <sys/acl.h>

     acl_t
     acl_copy_int(const void *buf_p);

DESCRIPTION

     The acl_copy_int() function copies an exportable, contiguous, persistent form of an ACL,
     pointed to by buf_p, to the internal representation.

     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
     returned by acl_copy_int() as an argument.

RETURN VALUE

     Upon success, the acl_copy_int() function returns a pointer that references the ACL in
     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 acl_copy_int() function returns a value of
     (acl_t)NULL and sets errno to the corresponding value:

     [EINVAL]           The buffer pointed to by the argument buf_p does not contain a valid
                        external form ACL.

     [ENOMEM]           The ACL working storage 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)
