ACL_DUP(3) BSD Library Functions Manual ACL_DUP(3)
acl_dup — duplicate an ACL
Linux Access Control Lists library (libacl, -lacl).
#include <sys/types.h>
#include <sys/acl.h>
acl_t
acl_dup(acl_t acl);
The acl_dup() function returns a pointer to a copy of the ACL pointed
to by 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 call‐
ing acl_free(3) with the (void*)acl_t returned by acl_dup() as an argu‐
ment.
On success, this function returns a pointer to the working storage. On
error, a value of (acl_t)NULL is returned, and errno is set appropri‐
ately.
If any of the following conditions occur, the acl_dup() function
returns a value of (acl_t)NULL and sets errno to the corresponding
value:
[EINVAL] The argument acl is not a valid pointer to an ACL.
[ENOMEM] The acl_t to be returned requires more memory than
is allowed by the hardware or system-imposed memory
management constraints.
