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 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).
