OS_TLS OS_TLS_GetValue (OS_TCB *p_tcb,
OS_TLS_ID id,
OS_ERR *p_err); |
Arguments
p_tcb
is a pointer to the OS_TCB of the task you wish to retrieve the TLS from. You will get a copy of the p_tcb->TLS_Tbl[id] entry and of course, the entry will not be changed.
...
- You cannot call
OS_TLS_GetValue()for a task until that task gets created.
