pthread_self(3)         Library Functions Manual         pthread_self(3)

НАЗВАНИЕ

       pthread_self - obtain ID of the calling thread

БИБЛИОТЕКА

       POSIX threads library (libpthread, -lpthread)

СИНТАКСИС

       #include <pthread.h>

       pthread_t pthread_self(void);

ОПИСАНИЕ

       The pthread_self() function returns the ID of the calling thread.
       This is the same value that is returned in *thread in the
       pthread_create(3) call that created this thread.

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       This function always succeeds, returning the calling thread's ID.

ОШИБКИ

       This function always succeeds.

СТАНДАРТЫ

       POSIX.1-2008.

ИСТОРИЯ

       POSIX.1-2001.

ПРИМЕЧАНИЯ

       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).
