Member Function Documentation

Uint32 Tup_varsize_page::alloc_record	(	Uint32	size,
		Tup_varsize_page *	temp,
		Uint32	chain
	)

Alloc record from page, return page_idx temp is used when having to reorg page before allocating

Definition at line 250 of file tuppage.cpp.

Uint32 Tup_varsize_page::alloc_record	(	Uint32	page_idx,
		Uint32	size,
		Tup_varsize_page *	temp
	)

Alloc page_idx from page, return page_idx temp is used when having to reorg page before allocating

We need to expand directory
