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
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 con-
straints.
STANDARDS

ACL_FROM_TEXT(3) BSD Library Functions Manual ACL_FROM_TEXT(3)NAME
acl_from_text -- create an ACL from text
LIBRARY
Linux Access Control Lists library (libacl, -lacl).
SYNOPSIS
#include <sys/types.h>
#include <sys/acl.h>
acl_t
acl_from_text(const char *buf_p);
DESCRIPTION
The acl_from_text() function converts the text form of the ACL referred to by buf_p into the internal form of an ACL and returns a pointer to
the working storage that contains the ACL. The acl_from_text() function accepts as input the long text form and short text form of an ACL as
described in acl(5).
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_from_text() as an argument.
RETURN VALUE
Upon successful completion, this function returns a pointer to the working storage. Otherwise, a value of (acl_t)NULL is returned, and errno
is set to indicate the error.
ERRORS
If any of the following conditions occur, the acl_from_text() function returns a value of (acl_t)NULL and sets errno to the corresponding
value:
[EINVAL] The argument buf_p cannot be translated into an ACL.
[ENOMEM] The acl_t to be returned requires more memory than is allowed by the hardware or system-imposed memory management con-
straints.

Hello for all,
I am testing the behavior of a 32 bit application running on Solaris 5.10 (SPARC), and realize it reaches 4GB of memory and then crashes.
