EXTENDS_TYPE_OF(A, MOLD) (Fortran 2003)

Purpose

Inquires whether the dynamic type of A is an extension type of the dynamic type of MOLD.

Class

Inquiry function

Argument type and attributes

A

An INTENT(IN) argument of extensible type. If the actual argument corresponding to A is a pointer, the pointer must not have an undefined association status.

MOLD

An INTENT(IN) argument of extensible type. If the actual argument corresponding to MOLD is a pointer, the pointer must not have an undefined association status.

Result type and attributes

Default logical scalar

Result value

• If MOLD is unlimited polymorphic and is a disassociated pointer or an allocatable argument that is deallocated, the result is true.
• Otherwise, if A is unlimited polymorphic and is either a disassociated pointer or an allocatable argument that is deallocated, the result is false.
• Otherwise, if the dynamic type of A is an extension type of the dynamic type of MOLD, the result is true.
• Otherwise, the result is false.
