Member Typedef Documentation

int4_t sthread_base_t::timeout_in_ms

Timeout in milliseconds if > 0.

sthread_t blocking methods take a timeout in milliseconds. If the value is < 0, then it's expected to be a member of the enumeration type timeout_t.

Member Enumeration Documentation

enum sthread_base_t::timeout_t

Special values for timeout_in_ms.

sthreads package recognizes 2 WAIT_* values: == WAIT_IMMEDIATE and != WAIT_IMMEDIATE.

If it's not WAIT_IMMEDIATE, it's assumed to be a positive integer (milliseconds) used for the select timeout. WAIT_IMMEDIATE: no wait WAIT_FOREVER: may block indefinitely The user of the thread (e.g., sm) had better convert timeout that are negative values (WAIT_* below) to something >= 0 before calling block().

All other WAIT_* values other than WAIT_IMMEDIATE are handled by sm layer: WAIT_SPECIFIED_BY_THREAD: pick up a timeout_in_ms from the smthread. WAIT_SPECIFIED_BY_XCT: pick up a timeout_in_ms from the transaction. Anything else: not legitimate.
