◆ STCB

using STCB = void (void *, StoreIOBuffer)

A storeClientCopy() callback function.

Upon storeClientCopy() success, StoreIOBuffer::flags.error is zero, and

HTTP response headers (if any) are available via MemObject::freshestReply();
HTTP response body bytes (if any) are available via StoreIOBuffer.

STCB callbacks may use response semantics to detect certain EOF conditions. Callbacks that expect HTTP headers may call store_client::atEof(). Similar to clientStreamCallback() callbacks, callbacks dedicated to receiving HTTP bodies may use zero StoreIOBuffer::length as an EOF condition.

Errors are indicated by setting StoreIOBuffer flags.error.

Function Documentation

◆ storeClientCopy()

void storeClientCopy	(	store_client *	sc,
		StoreEntry *	e,
		StoreIOBuffer	copyInto,
		STCB *	callback,
		void *	data
	)

Asynchronously read HTTP response headers and/or body bytes from Store.

The requested zero-based HTTP body offset is specified via the StoreIOBuffer::offset field. The first call (for a given store_client object) must specify zero offset.

The requested HTTP body portion size is specified via the StoreIOBuffer::length field. The function may return fewer body bytes.

See STCB for result delivery details.
