stream_io_creator_t Struct Reference

Owner-facing creator object for standard I/O-oriented streams. More...

#include <stream_io_creator.h>

Data Fields
stream_status_t(*	create )(const void *ud, stream_io_kind_t kind, stream_t **out)
	Create a standard I/O-oriented stream.
void *	ud
	Opaque context bound to create.

Detailed Description

A stream_io_creator_t packages:

• a creation callback,
• opaque user data bound to that callback.

Such an object is typically prepared by the Composition Root and then injected into owner-side runtime code that needs to create standard input/output/error stream_t instances without depending directly on factory wiring details.
