## Module

USE, INTRINSIC :: ISO_C_BINDING

## Syntax

result = C_ASSOCIATED(c_ptr_1[, c_ptr_2])

c_ptr_1 | (Input) Is a scalar of derived type C_PTR or C_FUNPTR.
c_ptr_2 | (Optional; input) Is a scalar of the same type as c_ptr_1.

## Results

The result is a scalar of type default logical. The result value is one of the following:

- If only c_ptr_1 is specified, the result is false if c_ptr_1 is a C null pointer; otherwise, the result is true.

- If c_ptr_2 is specified, the result is false if c_ptr_1 is a C null pointer. The result is true if c_ptr_1 is equal to c_ptr_2; otherwise, the result is false.
