ACL_COPY_INT(3)		 BSD Library Functions Manual	      ACL_COPY_INT(3)

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 call-
     ing 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 refer-
     ences 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 man-
			agement constraints.

STANDARDS
     IEEE Std 1003.1e draft 17 (“POSIX.1e”, abandoned)
