Detailed Description

The mother base class for most types.

Attention:

These basic 1,2,4, and 8-byte types predate the now-standard "u8", etc. When these were developed, we used the count to refer to bytes, not bits. So for new users, this might take a bit of getting-used-to.

	Comparison Operators.
enum	lock_mode_t
	Lock modes for the Storage Manager. Note: Capital letters are used to match common usage in DB literature Note: Values MUST NOT CHANGE since order is significant. Locking.
enum	lock_duration_t
	Duration for locks Locking.
enum	vote_t
	Votes for two-phase commit. vote_readonly : storage manager will return this from ss_m::prepare_xct when transaction has not logged anything. See also ss_m::force_vote_readonly. vote_abort : Might be returned if error occurs. vote_commit : Usual result of prepare. Distributed Transactions: Two-Phase Commit.

Member Function Documentation

w_base_t::int8_t w_base_t::strtoi8	(	const char *	,
		char **	end = 0,
		int	base = 0
	)			[static]

Convert string to 8-byte integer.

strtoi8 acts like strto[u]ll with the following two exceptions: the only bases supported are 0, 8, 10, 16; errno is not set

Here is the caller graph for this function:

w_base_t::uint8_t w_base_t::strtou8	(	const char *	,
		char **	end = 0,
		int	base = 0
