Field Documentation

◆ current

thread_t* nil_os_instance::current

Pointer to the running thread.

Definition at line 557 of file nil/include/ch.h.

◆ next

thread_t* nil_os_instance::next

Pointer to the next thread to be executed.

Note: This pointer must point at the same thread pointed by current or to an higher priority thread if a switch is required.

Definition at line 563 of file nil/include/ch.h.

◆ systime

volatile systime_t nil_os_instance::systime

System time.

Definition at line 568 of file nil/include/ch.h.

◆ lasttime

systime_t nil_os_instance::lasttime

System time of the last tick event.

Definition at line 574 of file nil/include/ch.h.

◆ nexttime

systime_t nil_os_instance::nexttime

Time of the next scheduled tick event.

Definition at line 578 of file nil/include/ch.h.

◆ isr_cnt

cnt_t nil_os_instance::isr_cnt

ISR nesting level.

Definition at line 584 of file nil/include/ch.h.

◆ lock_cnt

cnt_t nil_os_instance::lock_cnt

Lock nesting level.

Definition at line 588 of file nil/include/ch.h.

◆ dbg_panic_msg

const char* volatile nil_os_instance::dbg_panic_msg

Panic message.

Note: This field is only present if some debug options have been activated.; Accesses to this pointer must never be optimized out so the field itself is declared volatile.

Definition at line 598 of file nil/include/ch.h.

◆ threads

thread_t nil_os_instance::threads[CH_CFG_MAX_THREADS+1]

Thread structures for all the defined threads.

Definition at line 603 of file nil/include/ch.h.
