Here is the caller graph for this function:

CVMFS_EXPORT bool CreatePidNamespace ( int * fd_parent )

The fd_parent file descriptor, if passed, is the read end of a pipe whose write end is connected to the parent process. This gives the namespace's init process a means to know its pid in the context of the parent namespace.
