I assume you want to wait until you find a caller before exporting the other
functions from this file.

 
 // For a given process |pid|, look through all its threads and find the first
 // thread with /proc/[pid]/task/[thread_id]/syscall whose first N bytes matches
 // |expected_data|, where N is the length of |expected_data|.
 // Returns the thread id or -1 on error.
 pid_t FindThreadIDWithSyscall(pid_t pid, const std::string& expected_data);
 
 }  // namespace base
 
 #endif  // BASE_LINUX_UTIL_H_
