The function copies the ACL pointed to by from system-managed space to the user managed space pointed to by The parameter represents the size in bytes of the buffer pointed to by The format of the ACL placed in the buffer pointed to by is a contiguous, persistent data item, the format of which is unspecified. It is the responsibility of the invoker to allocate an area large enough to hold the copied ACL. The size of the exportable, contiguous, persistent form of the ACL may be obtained by invoking the function.

Any ACL entry descriptors that refer to an entry in the ACL referenced by continue to refer to those entries. Any existing ACL pointers that refer to the ACL referenced by continue to refer to the ACL.

Upon success, this function returns the number of bytes placed in the buffer pointed to by On error, a value of is returned and is set appropriately.

If any of the following conditions occur, the function returns a value of and sets to the corresponding value:

• EINVAL The parameter is zero or negative.

The argument is not a valid pointer to an ACL.

The ACL referenced by contains one or more improperly formed ACL entries, or for some other reason cannot be translated into the external form of an ACL.

ERANGE The parameter is greater than zero but smaller than the length of the contiguous, persistent form of the ACL.
