#ifndef MEMORY_H
#define MEMORY_H 1
/* Memory usage monitor.
*
* This is intended to be called as part of a daemon's main loop. After some
* time to allow the daemon to allocate an initial memory usage, it logs some
* memory usage information (most of which must actually be provided by the
* client). At intervals, if the daemon's memory usage has grown
* significantly, it again logs information.
*
* The monitor also has a unixctl interface.
*
* Intended usage in the program's main loop is like this:
*
* for (;;) {
* memory_run();
* if (memory_should_report()) {
* struct simap usage;
*
* simap_init(&usage);
* ...fill in 'usage' with meaningful statistics...
* memory_report(&usage);
* simap_destroy(&usage);
* }
*
* ...
*
* memory_wait();
* poll_block();
* }
