CommandResult * parse_command ( const char * input,
yajl_gen gen,
ipc_client * client )

Parses and executes the given command.

If a caller-allocated yajl_gen is passed, a json reply will be generated in the format specified by the ipc protocol. Pass NULL if no json reply is required.

Free the returned CommandResult with command_result_free().
