Описание (Description)

       This is the same value that is returned in *thread in the
       pthread_create(3) call that created this thread.

Примечание (Note)

POSIX.1 allows an implementation wide freedom in choosing the
       type used to represent a thread ID; for example, representation
       using either an arithmetic type or a structure is permitted.
       Therefore, variables of type pthread_t can't portably be compared
       using the C equality operator (==); use pthread_equal(3) instead.

       Thread identifiers should be considered opaque: any attempt to
       use a thread ID other than in pthreads calls is nonportable and
       can lead to unspecified results.

       Thread IDs are guaranteed to be unique only within a process.  A
       thread ID may be reused after a terminated thread has been
       joined, or a detached thread has terminated.

       The thread ID returned by pthread_self() is not the same thing as
       the kernel thread ID returned by a call to gettid(2).
