Subject: command.c: Improve get_status().
X-Git-Tag: v0.4.11~14^2~5
X-Git-Url: http://git.tue.mpg.de/?a=commitdiff_plain;h=3667d75edd30f45f6b909bcf5203689c866a77b5;p=paraslash.git

command.c: Improve get_status().

We know exactly the number of bytes in the result buffer. By returning
this information, the caller can use sc_send_bin_buffer() instead of
sc_send_buffer(), which safes one strlen() call.
