Either at the end of the + transmission or everytime SIGUSR1 is received. Quite useful to ask + lengthy opertions how much data has been transferred yet, i.e. when + writing tapes. Reports are done in bytes/sec and if appropriate in + KB/sec or MB/sec, where 1K = 1024. +- SIGHUP causes a clean shutdown before EOF on input. +- Build-in support to write its PID to a file. +- Build-in support for fifos. Example usage is a 'pseudo-device', + something that sinks or delivers data at an appropriate rate, but + looks like a file, i.e. if you test soundcard software. +- Built-in data creation and sink, no more redirection of + /dev/null and /dev/zero. These special devices speed varies greatly + amoung operating systems, redirecting from it isn't appropriate + benchmarking and a waste of resources anyway. +- "gcc -Wall" clean source code, serious effort taken to avoid + undefined behavior in ANSI C or POSIX, except long long + is required. Limiting and reporting works on data amounts > 4 GB. |
