FFI::cast
(PHP 7 >= 7.4.0, PHP 8)
FFI::cast — Performs a C type cast
Description
FFI::cast() creates a new FFI\CData
object, that references the same C data structure, but is associated with a different type.
The resulting object does not own the C data, and the source ptr
must survive the result. The C type may be specified as a string with any
valid C type declaration or as FFI\CType object, created before.
Any type declared for the instance is allowed.
Parameters
type-
A valid C declaration as string, or an instance of FFI\CType
which has already been created.
ptr-
The handle of the pointer to a C data structure.
Return Values
Returns the freshly created FFI\CData object.
