Type Alias CastSource

Interpret a pointer as a different type.

Python equivalent: ctypes.cast

When the target is a PointerTypeDef, returns a PointerInstance with .contents and [index] access — equivalent to Python's cast(c_void_p(addr), POINTER(MyStruct)). A FuncPtrFactory target returns a caller with that prototype.

Param: ptr

Memory, a pointer/address, or a native function/callback

Param: targetType

The target type (primitive, struct, POINTER or CFUNCTYPE)

Example: Cast to POINTER for typed array access

// Python: cast(c_void_p(addr), POINTER(MyStruct))
const pValues = cast(col.pADsValues, POINTER(ADSVALUE));
for (let i = 0; i < col.dwNumValues; i++) {
  console.log(pValues[i].dwType);
}

Example: Cast to primitive type

const floatVal = cast(intBuf, c_float);
