Detailed Description

Platform-independent base class for running threads.

A Thread object manages one thread of control within the program. Threads begin executing with run(). Operational threads can be created by creating a derived class and reimplement function run().

Threads are reference-counted objects. Their allocation and destruction can be automatically managed with Thread_var.

Member Function Documentation

◆ current()

static Thread* GEO::Thread::current ( )
static

Gets the current thread.

Returns
A pointer to the instance of the currently running thread. If not running multiple threads, returns nullptr.

◆ current_id()

static index_t GEO::Thread::current_id ( )
inlinestatic

Gets the identifier of the current thread.

Returns
the identifier of the current thread, i.e. an unsigned integer in the range [0, N-1] where N denotes the number of currently running threads. If not running multiple threads, returns 0.

Definition at line 107 of file process.h.

◆ id()

index_t GEO::Thread::id ( ) const
inline

Gets the identifier of this thread.

Returns
the identifier of the thread, i.e. an unsigned integer in the range [0, N-1] where N denotes the number of currently running threads.
