This class represents a running version of a procedure or frame in an application. When the procedure or frame terminates, OpenROAD frees the object. The ProcExec and FrameExec objects give you access to runtime information about the current state of the procedure or frame. Whenever your application calls a frame or procedure, OpenROAD creates a ProcExec (for procedures) or FrameExec (for frames) object. (The FrameExec object is actually a subclass of ProcExec.)
