Subject: procd: update procd.sh to disallow signal-numbers, enforce signal-names
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b54cbad6ef2fe592c1624915a84190759620f91c;p=openwrt%2Fstaging%2Fjow.git

procd: update procd.sh to disallow signal-numbers, enforce signal-names

A given signal-name is now converted to the corresonding number. In general
it's good style to use names (readability) and it's more portable: signal
numbers can be architecture-dependent, so we are more safe giving names.

A real world example is signal 10, which is BUS on ramips and USR1 on PPC.

All users of 'procd_send_signal' must change their code to reflect this.
