Methods
with
#define with(...)
Perform operations in between start and stop.
start
void start(var self);
Start the object self.
stop
void stop(var self);
Stop the object self.
join
void join(var self);
Block and wait for the object self to stop.
running
bool running(var self);
Check if the object self is running.
Examples
Usage
var x = new(Mutex);
start(x); /* Lock Mutex */
print("Inside Mutex!\n");
stop(x); /* unlock Mutex */
Scoped
var x = new(Mutex);
with (mut in x) { /* Lock Mutex */
print("Inside Mutex!\n");
} /* unlock Mutex */
Start
Can be started or stopped
The Start class can be implemented by types which provide an abstract notion of a started and stopped state. This can be real processes such as Thread, or something like File where the on/off correspond to if the file is open or not.
The main nicety of the Start class is that it allows use of the with macro which performs the start function at the opening of a scope block and the stop function at the end.
Definition
struct Start {
void (*start)(var);
void (*stop)(var);
void (*join)(var);
bool (*running)(var);
};
