Имя (Name)
acl_copy_int — copy an ACL from external to internal representation
Библиотека (Library)
Linux Access Control Lists library (libacl, -lacl).
Синопсис (Synopsis)
#include <sys/types.h>
#include <sys/acl.h>
acl_t
acl_copy_int(const void *buf_p);
Описание (Description)
The acl_copy_int() function copies an exportable, contiguous,
persistent form of an ACL, pointed to by buf_p, to the internal
representation.
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 returned by
acl_copy_int() as an argument.
Возвращаемое значение (Return value)
Upon success, the acl_copy_int() function returns a pointer that
references the ACL in working storage. On error, a value of
(acl_t)NULL is returned, and errno is set appropriately.
Ошибки (Error)
If any of the following conditions occur, the acl_copy_int()
function returns a value of (acl_t)NULL and sets errno to the
corresponding value:
[EINVAL] The buffer pointed to by the argument buf_p does
not contain a valid external form ACL.
[ENOMEM] The ACL working storage requires more memory
than is allowed by the hardware or system-
imposed memory management constraints.
