    Command:

    pthread_self

    
    
    

    SYNOPSIS

           #include <pthread.h>
    
           pthread_t pthread_self(void);
    
           Compile and link with -pthread.
    
    
    

    DESCRIPTION

           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.
    
    
    

    RETURN VALUE

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

    ERRORS

           This function always succeeds.
    
    
    

    CONFORMING TO

           POSIX.1-2001.
    
    
    

    NOTES

           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).
