NAME

gettid − get thread ID

SYNOPSIS

#include <sys/types.h>

tid_t gettid ()

DESCRIPTION

gettid returns the thread ID of the calling thread, guaranteed to be non-zero.  Beware that thread IDs are not the same as process IDs. 

NOTE

CX/UX does not yet support a lightweight process abstraction.  Currently, each process contains exactly one thread of execution.  The question of how to coordinate a collection of processes sharing portions of their address spaces with shared memory segments is very similar to the question of how to coordinate a collection of threads sharing an entire address space.  Using thread IDs, CX/UX provides a set of real-time synchronization primitives applicable to the former environment today and the latter environment in the future.
