These functions are fully supported in this release:
ER sus_tsk
(ID tskid);ER rsm_tsk
(ID tskid);ER frsm_tsk
(ID tskid);ER slp_tsk
(void);ER tslp_tsk
(TMO tmout);ER wup_tsk
(ID tskid);ER can_wup
(INT *p_wupcnt, ID tskid);The following conditions are only checked for, and only return errors if CYGSEM_UITRON_BAD_PARAMS_RETURN_ERRORS is enabled (see the section called Option: Return Error Codes for Bad Params in Chapter 18):
invalid tskid; less than 1 or greater than CYGNUM_UITRON_TASKS (the section called Option: Number of tasks in Chapter 18) returns E_ID
wup_tsk(), sus_tsk(), rsm_tsk(), frsm_tsk() on the calling task returns E_OBJ
dispatching is enabled in tslp_tsk() and slp_tsk(), or E_CTX
tmout must be positive, otherwise E_PAR
return value pointer in can_wup() is a valid pointer, or E_PAR
The following conditions are checked for, and can return error codes, regardless of the setting of CYGSEM_UITRON_BAD_PARAMS_RETURN_ERRORS:
When create and delete functions cre_tsk() and del_tsk() are supported, all calls which use a valid task ID number check that the task exists; if not, E_NOEXS is returned
sus_tsk(): the task must not be dormant, else E_OBJ
frsm/rsm_tsk(): the task must be suspended, else E_OBJ
tslp/slp_tsk(): return codes E_TMOUT, E_RLWAI and E_DLT are returned depending on the reason for terminating the sleep
wup_tsk() and can_wup(): the task must not be dormant, or E_OBJ is returned
