LIBRARY


.Lb libc

SYNOPSIS


.In sys/types.h
.In 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.

IMPLEMENTATION NOTES


.Fx Ns ’s support for POSIX.1e interfaces and features is still under development at this time.

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 constraints.
