◆ spool_txt_printf()

static void spool_txt_printf	(	struct config_strlist_head *	txt,
		const char *	format,
			...
	)

static

Print item to spool list.

On alloc failure the list is as before.

◆ dump_cache()

int dump_cache	(	RES *	ssl,
		struct worker *	worker
	)

Dump cache(s) to text.

Parameters

ssl	to print to
worker	worker that is available (buffers, etc) and has ptrs to the caches.

Returns: false on ssl print error.
