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