示例3: Put

/*
The "put" command is for any process that wants to insert a job into the queue.
It comprises a command line followed by the job body:

put <pri> <delay> <ttr> <bytes>\r\n
<data>\r\n

It inserts a job into the client's currently used tube (see the "use" command
below).

 - <pri> is an integer < 2**32. Jobs with smaller priority values will be
   scheduled before jobs with larger priorities. The most urgent priority is 0;
   the least urgent priority is 4,294,967,295.

 - <delay> is an integer number of seconds to wait before putting the job in
   the ready queue. The job will be in the "delayed" state during this time.

 - <ttr> -- time to run -- is an integer number of seconds to allow a worker
   to run this job. This time is counted from the moment a worker reserves
   this job. If the worker does not delete, release, or bury the job within
   <ttr> seconds, the job will time out and the server will release the job.
   The minimum ttr is 1. If the client sends 0, the server will silently
   increase the ttr to 1.

 - <bytes> is an integer indicating the size of the job body, not including the
   trailing "\r\n". This value must be less than max-job-size (default: 2**16).

 - <data> is the job body -- a sequence of bytes of length <bytes> from the
   previous line.

After sending the command line and body, the client waits for a reply, which
may be:

 - "INSERTED <id>\r\n" to indicate success.

   - <id> is the integer id of the new job

 - "BURIED <id>\r\n" if the server ran out of memory trying to grow the
   priority queue data structure.

   - <id> is the integer id of the new job

 - "EXPECTED_CRLF\r\n" The job body must be followed by a CR-LF pair, that is,
   "\r\n". These two bytes are not counted in the job size given by the client
   in the put command line.

 - "JOB_TOO_BIG\r\n" The client has requested to put a job with a body larger
   than max-job-size bytes.

 - "DRAINING\r\n" This means that the server has been put into "drain mode"
   and is no longer accepting new jobs. The client should try another server
   or disconnect and try again later.
