user: What is the c source code of the assembly code below?

```asm

tool: D9: %s [--help]

This program acts as an interactive client for membroker, allowing
one to request and return pages to the membroker pool, and query
the current state of membroker and available pages.

Below is a summary of the commands available:
  reserve [pages]: Makes a high-anxiety request for memory pages from
                   membroker. Membroker will return either 0 pages or
                   the full amount requested, and will make every effort
                   to procure memory from other clients, possibly
                   blocking for an indefinitely long period of time.

  reserve-all      Iteratively makes high anxiety requests to membroker,
                   eventually reserving all possible pages.

  request [pages]: Makes a low-anxiety request for memory pages from
                   membroker. Membroker may return fewer pages than
                   requested and will only attempt to procure easily
                   available memory but will not block indefinitely.

  return [pages]:  Return a number of pages previously requested to
                   membroker.

  query:           Print this client's current page balance (i.e. the
                   number of source pages it has made available to
                   membroker - the number of pages membroker has
                   borrowed + the number of pages the client has
                   borrowed)

  query-server:    print the total number of pages currently in
                   membroker's own pool.

  query-total:     print the total number of pages membroker could
                   theorectically loan out; equal to the sum of its own
                   pages plus the maximum number of source pages
                   contributed by all the source clients.

  end:             Terminate the connection to membroker and exit
