Linux Access Control Lists library (libacl, -lacl).
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:
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.
The
parameter is greater than zero but smaller than the length of the contiguous, persistent form of the ACL.
