Modules | |
Contiki processes | |
A process in Contiki consists of a single Protothreads protothread. | |
Event timers | |
Event timers provides a way to generate timed events. | |
The Contiki service mechanism | |
The Contiki service mechanism enables cross-process functions. | |
Argument buffer | |
The argument buffer can be used when passing an argument from an exiting process to a process that has not been created yet. | |
The Contiki program loader | |
The Contiki program loader is an abstract interface for loading and starting programs. | |
Clock library | |
The clock library is the interface between Contiki and the platform specific clock functionality. | |
Multi-threading library | |
The event driven Contiki kernel does not provide multi-threading by itself - instead, preemptive multi-threading is implemented as a library that optionally can be linked with applications. | |
Protothreads | |
Protothreads are a type of lightweight stackless threads designed for severly memory constrained systems such as deeply embedded systems or sensor network nodes. | |
The Contiki file system interface | |
The Contiki file system interface (CFS) defines an abstract API for reading directories and for reading and writing files. | |
Timer library | |
The Contiki kernel does not provide support for timed events. | |
Return values | |
#define | PROCESS_ERR_OK 0 |
Return value indicating that an operation was successful. | |
#define | PROCESS_ERR_FULL 1 |
Return value indicating that the event queue was full. | |
Service declaration and defition | |
#define | SERVICE_INTERFACE(name, interface) |
Define the name and interface of a service. | |
#define | SERVICE(name, service_name,) |
Define an implementation of a service interface. | |
Functions called from application programs | |
void | etimer_set (struct etimer *et, clock_time_t interval) |
Set an event timer. | |
void | etimer_reset (struct etimer *et) |
Reset an event timer with the same interval as was previously set. | |
void | etimer_restart (struct etimer *et) |
Restart an event timer from the current point in time. | |
void | etimer_adjust (struct etimer *et, int td) |
Adjust the expiration time for an event timer. | |
clock_time_t | etimer_expiration_time (struct etimer *et) |
Get the expiration time for the event timer. | |
clock_time_t | etimer_start_time (struct etimer *et) |
Get the start time for the event timer. | |
int | etimer_expired (struct etimer *et) |
Check if an event timer has expired. | |
void | etimer_stop (struct etimer *et) |
Stop a pending event timer. | |

Return value indicating that an operation was successful. This value is returned to indicate that an operation was successful. Definition at line 75 of file process.h. Referenced by process_post(), and PROCESS_THREAD(). |
|
Define an implementation of a service interface.
|
|
Define the name and interface of a service. This statement defines the name and interface of a service.
