cstream is a general-purpose stream-handling tool like UNIX' dd,
|
|
usually used in commandline-constructed pipes.
|
|
|
|
- Sane commandline switch syntax.
|
|
- Exact throughput limiting, on the incoming side.
|
|
- Precise throughput reporting. Either at the end of the
|
|
transmission or everytime SIGUSR1 is received. Quite useful to ask
|
|
lengthy operations 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
|
|
among 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.
