Subject: ucode: respect all arguments passed to send()
X-Git-Url: http://git.openwrt.org/?a=commitdiff_plain;h=63413578a8e32e90cbb01d8bffff7f6db5a3a7a5;p=project%2Fuhttpd.git

ucode: respect all arguments passed to send()

Similar to ucode's print() this now prints any given values to stdout:
uhttpd.send(a, b, c, "\n");
