FFI::cast

PHP function Edit on GitHub ✎

(PHP 7 >= 7.4.0, PHP 8)

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.
