When no clients are running, fishd will automatically shut down and save. +\subsection fishd-commands Commands + +Fishd works by sending and receiving commands. Each command is ended +with a newline. These are the commands supported by fishd: + +<pre>set KEY:VALUE +set_export KEY:VALUE +</pre> + +These commands update the value of a variable. The only difference +between the two is that <tt>set_export</tt>-variables should be +exported to children of the process using them. The variable value may +be escaped using C-style backslash escapes. In fact, this is required +for newline characters, which would otherwise be interpreted as end of +command. + +<pre>erase KEY +</pre> + +Erase the variable with the specified name. + +<pre>barrier +barrier_reply +</pre> + +A \c barrier command will result in a barrier_reply being added to +the end of the senders queue of unsent messages. These commands are +used to synchronize clients, since once the reply for a barrier +message returns, the sender can know that any updates available at the +time the original barrier request was sent have been received. + */ #include "config.h" |
