ACL_DUP(3) BSD Library Functions Manual ACL_DUP(3)NAMEacl_dup — duplicate an ACL
Standard C Library (libc, -lc)
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.
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.
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 man‐
