ACL_DUP(3)						   BSD Library Functions Manual 						ACL_DUP(3)

NAME

     acl_dup -- duplicate an ACL

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

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

     acl_t
     acl_dup(acl_t acl);

DESCRIPTION

     The acl_dup() function returns a pointer to a copy of the ACL pointed to by the argument acl.

     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.

     Any existing ACL pointers that refer to the ACL referred to by acl shall continue to refer to the ACL.

RETURN VALUES

     Upon successful completion, this function shall return a pointer to the duplicate ACL.  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]		Argument acl does not point to a valid ACL.

     [ENOMEM]		The acl_t to be returned requires more memory than is allowed by the hardware or system-imposed memory management con-
			straints.

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 con-
			straints.
