NAMEpthread_self - obtain ID of the calling thread
#include <pthread.h> pthread_t pthread_self(void); Compile and link with -pthread.
DESCRIPTIONThe 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 VALUEThis function always succeeds, returning the calling thread's ID.
ERRORSThis function always succeeds.
NOTESPOSIX.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 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).
