Data Structures | |
struct | rtimer |
Representation of a real-time task. More... | |
Macros | |
#define | RTIMER_CLOCK_SIZE 4 |
The rtimer size (in bytes) | |
#define | RTIMER_SECOND RTIMER_ARCH_SECOND |
Number of rtimer ticks for 1 second. | |
#define | rtimer_init() |
Initialize the real-time scheduler. | |
#define | RTIMER_NOW() |
Get the current clock time. | |
#define | RTIMER_TIME(task) |
Get the time that a task last was executed. | |
#define | RTIMER_BUSYWAIT_UNTIL_ABS(cond, t0, max_time) |
Busy-wait until a condition. | |
#define | RTIMER_BUSYWAIT_UNTIL(cond, max_time) |
Busy-wait until a condition for at most max_time. | |
#define | RTIMER_BUSYWAIT(duration) RTIMER_BUSYWAIT_UNTIL(0, duration) |
Busy-wait for a fixed duration. | |
Enumerations | |
enum | { RTIMER_OK , RTIMER_ERR_FULL , RTIMER_ERR_TIME , RTIMER_ERR_ALREADY_SCHEDULED } |
TODO: we need to document meanings of these symbols. More... | |
Functions | |
int | rtimer_set (struct rtimer *task, rtimer_clock_t time, rtimer_clock_t duration, rtimer_callback_t func, void *ptr) |
Post a real-time task. | |
void | rtimer_run_next (void) |
Execute the next real-time task and schedule the next task, if any. | |
Architecture-dependent symbols | |
The functions declared in this section must be defined in architecture-dependent implementation of rtimer. Alternatively, they can be defined as macros in rtimer-arch.h. In addition, the architecture-dependent header (rtimer-arch.h) must define the following macros.
| |
void | rtimer_arch_init (void) |
Initialized the architecture-dependent part of rtimer. | |
void | rtimer_arch_schedule (rtimer_clock_t t) |
Schedules an rtimer task to be triggered at time t. | |
