Member Function Documentation

virtual void Test_MDL_context_owner::enter_cond ( mysql_cond_t *  cond, mysql_mutex_t *  mutex, const PSI_stage_info *  stage, PSI_stage_info *  old_stage, const char *  src_function, const char *  src_file, int  src_line  )

inlinevirtual

Enter a condition wait. For enter_cond() / exit_cond() to work the mutex must be held before enter_cond(); this mutex is then released by exit_cond(). Usage must be: lock mutex; enter_cond(); your code; exit_cond().

Parameters

	cond	the condition to wait on
	mutex	the associated mutex
[in]	stage	the stage to enter, or NULL
[out]	old_stage	the previous stage, or NULL
	src_function	function name of the caller
	src_file	file name of the caller
	src_line	line number of the caller
