#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 non-portable and can lead to unspecified results.
Thread IDs are only guaranteed to be unique 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).
