BTW: On unix (and linux) single writes on files opened with appends are guaranteed to append. And the syscall to "write" is atomic. Hence locking is not required. HOWEVER both the C code and the Python code use printf, and I confess that I am not 100% sure if a "fflush" is called when a printf includes a "\n". I'll take a look. |
