User space to copy the contiguous, persistent for of the
ACL into. Specifies the working storage, internal format
ACL to copy. Indicates the size of the buffer pointed to
NOTE: This function is based on Draft 13 of the POSIX
The acl_copy_ext() function copies the contents of the ACL
in internal working space format, pointed to by acl_d,
into the buffer pointed to by buf_p. The ACL copied into
the buffer is in contiguous, persistent formatxi and is
not NULL terminated.
Upon successful completion, the acl_copy_ext() function
returns the size of the ACL copied. Otherwise, a value of
-1 is returned and errno is set to indicate the error.
If any of the following conditions occur, the
acl_copy_ext() function sets errno to the corresponding
The size parameter is zero or negative. The ACL referenced
by acl_d contains one or more improperly formed ACL
entries, or for some other reason can not be translated
into contiguous format. The size parameter is greater
than 0, but smaller than the ACL to be copied.
