Overview ¶
Package threads provides SRFI-18 multithreading primitives.
Threads ¶
- make-thread, thread?
- thread-name, thread-specific, thread-specific-set!
- thread-start!, thread-yield!, thread-sleep!
- thread-terminate!, thread-join!
- current-thread
Mutexes ¶
- make-mutex, mutex?
- mutex-name, mutex-specific, mutex-specific-set!
- mutex-state
- mutex-lock!, mutex-unlock!
Condition Variables ¶
- make-condition-variable, condition-variable?
- condition-variable-name
- condition-variable-specific, condition-variable-specific-set!
- condition-variable-signal!, condition-variable-broadcast!
Time ¶
- current-time, time?, time->seconds, seconds->time
Exceptions ¶
- join-timeout-exception?, abandoned-mutex-exception?
- terminated-thread-exception?, uncaught-exception?
- uncaught-exception-reason
Use Extension or AddToRegistry to register all primitives.
Package threads provides SRFI-18 threading primitives.

Variables ¶
var AddToRegistry = Builder.AddToRegistry
AddToRegistry registers all threading primitives.
var Builder = registry.NewRegistryBuilder(addThreads, addMutexes, addConditionVariables, addTime)
Builder aggregates all threading registration functions.
var Extension = registry.NewDescribedExtension("threads", "Concurrency: SRFI-18 threads, mutexes, condition variables, channels.", AddToRegistry)
Extension is the threads extension.
var PrimConditionVariableQ = helpers.MakeTypePredicate(func(o values.Value) bool { _, ok := o.(*values.ConditionVariable) return ok })
PrimConditionVariableQ tests if an object is a condition variable (condition-variable? obj) -> boolean
var PrimMutexQ = helpers.MakeTypePredicate(func(o values.Value) bool { _, ok := o.(*values.Mutex) return ok })
PrimMutexQ tests if an object is a mutex (mutex? obj) -> boolean
var PrimThreadQ = helpers.MakeTypePredicate(func(o values.Value) bool { _, ok := o.(*values.Thread) return ok })
PrimThreadQ tests if an object is a thread (thread? obj) -> boolean
var PrimTimeQ = helpers.MakeTypePredicate(func(o values.Value) bool { _, ok := o.(*values.Time) return ok })
PrimTimeQ tests if an object is a time (time? obj) -> boolean
