Creates a C data structure
説明
public FFI\CDatanull FFI::new(FFI\CTypestring $type, bool $owned = true, bool $persistent = false)
パラメータ
-
type
-
type is a valid C declaration as string, or an
instance of FFI\CType which has already been created.
-
owned
-
Whether to create owned (i.e. managed) or unmanaged data. Managed data lives together
with the returned FFI\CData object, and is released when the
last reference to that object is released by regular PHP reference counting or GC.
Unmanaged data should be released by calling FFI::free,
when no longer needed.
-
persistent
-
Whether to allocate the C data structure permanently on the system heap (using
malloc), or on the PHP request heap (using emalloc).
戻り値
Returns the freshly created FFI\CData object,
or null on failure.
