stream_file_creator_t Struct Reference

Owner-facing creator object for file-backed streams. More...

#include <stream_file_creator.h>

Data Fields
stream_status_t(*	create )(const void *ud, const char *path, uint32_t flags, bool autoclose, stream_t **out)
	Create a file-backed stream.
void *	ud
	Opaque context bound to create.

Detailed Description

A stream_file_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 file-backed stream_t instances without depending directly on factory wiring details.

Field Documentation

create

stream_status_t(* stream_file_creator_t::create) (const void *ud, const char *path, uint32_t flags, bool autoclose, stream_t **out)

Parameters

[in]	ud	Opaque creator-owned context.
[in]	path	File path used to open or create the target stream backend.
[in]	flags	File opening flags forwarded to the underlying file-oriented adapter.
[in]	autoclose	Whether the created stream should close the underlying file resource automatically when the stream is destroyed.
[out]	out	Receives the created stream handle.

Returns

A stream_status_t describing the creation result.

ud

void* stream_file_creator_t::ud

This pointer typically hides Composition Root wiring details such as a factory reference and the associated adapter key.
