6.1. KERNEL INTERNAL STATE ACQUISITION FUNCTIONS 269 td inf tsk Reference Task Statistics [C Language Interface] ER ercd = td_inf_tsk ( ID tskid, TD_ITSK *pk_itsk, BOOL clr ); [Parameters] ID tskid Task ID (TSK SELF can be designated) TD ITSK* pk itsk Packet address for returning task statistics BOOL clr Task statistics clear flag [Return Parameters] ER ercd Error code pk itsk detail: RELTIM stime Cumulative system-level run time (ms) RELTIM utime Cumulative user-level run time (ms) [Error Codes] E OK E ID E NOEXS Normal completion ID number is invalid Object does not exist [Description] Gets task statistics. This is similar to tk inf tsk. When clr = TRUE (≠ 0), accumulated information is reset (cleared to 0) after getting the statistics. Copyright c○ 2002, 2003 by T-Engine Forum T-Kernel 1.B0.02
