PTHREAD_SELF(3) Linux Programmer's Manual PTHREAD_SELF(3)
pthread_self - obtain ID of the calling thread
#include <pthread.h>
pthread_t pthread_self(void);
Compile and link with -pthread.
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.
This function always succeeds, returning the calling thread's ID.
This function always succeeds.
POSIX.1-2001.
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).
