    With the "standard" implementation (the one you get if you do not
  do anything), it uses clone().

    It is pthread.h

    You can get the sources by typing

apt-get source libc6

  (this is a big collection of libraries, but it contains /lib/libpthread-2.7.so
  that implements pthread_* functions).

      Hope this helps,
