Quickest way to get thread id(tid?)?

[blah32]

What is the quickest way to get the thread id(tid) of the current thread in linux?

Specifically I use fedora 13. ...and I am talking about inside a C++ program.

There is a system call for this, but not a library call, so you have to use the syscall() interface to invoke the gettid() system call:

• #define _GNU_SOURCE
• #include unistd.h, sys/syscall.h and sys/types.h
• Call `syscall(SYS_gettid)', which returns a value of type pid_t

pthread_self() will return the thread id of the calling thread.
