Re: [Csnd-dev] [EXTERNAL] [Csnd-dev] strange string behaviour

There is no issue, the printout is what I would have expected.

Snew runs only at i-time, sprintfk/strcatk run at i-time and perf-time, printf only at perf-time.

i-time:
Snew >>>> ""
Sline >>>> "1\n"
Snew >>>> "1\n"

p-time:
Sline >>>> "1\n1\n"
Snew >>>> "1\n1\n1\n"
Sline =
1
1
Snew =
1
1
1
turnoff
