#define PT_BEGIN | ( | pt | ) |
Declare the start of a protothread inside the C function implementing the protothread.
This macro is used to declare the starting point of a protothread. It should be placed at the start of the function in which the protothread runs. All C statements above the PT_BEGIN() invokation will be executed each time the protothread is scheduled.
pt | A pointer to the protothread control structure. |
#define PT_END | ( | pt | ) |
Declare the end of a protothread.
This macro is used for declaring that a protothread ends. It must always be used together with a matching PT_BEGIN() macro.
pt | A pointer to the protothread control structure. |
#define PT_ENDED 3 |
#define PT_EXIT | ( | pt | ) |
Exit the protothread.
This macro causes the protothread to exit. If the protothread was spawned by another protothread, the parent protothread will become unblocked and can continue to run.
pt | A pointer to the protothread control structure. |
#define PT_EXITED 2 |
#define PT_INIT | ( | pt | ) |
Initialize a protothread.
Initializes a protothread. Initialization must be done prior to starting to execute the protothread.
pt | A pointer to the protothread control structure. |
#define PT_RESTART | ( | pt | ) |
Restart the protothread.
This macro will block and cause the running protothread to restart its execution at the place of the PT_BEGIN() call.
pt | A pointer to the protothread control structure. |
#define PT_SCHEDULE | ( | f | ) |
Schedule a protothread.
This function schedules a protothread. The return value of the function is non-zero if the protothread is running or zero if the protothread has exited.
f | The call to the C function implementing the protothread to be scheduled |
#define PT_SPAWN | ( | pt, | |
child, | |||
thread | |||
) |
Spawn a child protothread and wait until it exits.
This macro spawns a child protothread and waits until it exits. The macro can only be used within a protothread.
pt | A pointer to the protothread control structure. |
child | A pointer to the child protothread's control structure. |
thread | The child protothread with arguments |
#define PT_THREAD | ( | name_args | ) |
Declaration of a protothread.
This macro is used to declare a protothread. All protothreads must be declared with this macro.
name_args | The name and arguments of the C function implementing the protothread. |
#define PT_WAIT_THREAD | ( | pt, | |
thread | |||
) |
Block and wait until a child protothread completes.
This macro schedules a child protothread. The current protothread will block until the child protothread completes.
pt | A pointer to the protothread control structure. |
thread | The child protothread with arguments |
#define PT_WAIT_UNTIL | ( | pt, | |
condition | |||
) |
Block and wait until condition is true.
This macro blocks the protothread until the specified condition is true.
pt | A pointer to the protothread control structure. |
condition | The condition. |
Block and wait while condition is true.
This function blocks and waits while condition is true. See PT_WAIT_UNTIL().
pt | A pointer to the protothread control structure. |
cond | The condition. |
#define PT_WAITING 0 |
#define PT_YIELD | ( | pt | ) |
Yield from the current protothread.
This function will yield the protothread, thereby allowing other processing to take place in the system.
pt | A pointer to the protothread control structure. |
Yield from the protothread until a condition occurs.
pt | A pointer to the protothread control structure. |
cond | The condition. This function will yield the protothread, until the specified condition evaluates to true. |
#define PT_YIELDED 1 |
