-/*****************************************************************
- * ReadRequestFromClient
- *    Returns one request in client->requestBuffer.  The request
- *    length will be in client->req_len.  Return status is:
- *
- *    > 0  if  successful, specifies length in bytes of the request
- *    = 0  if  entire request is not yet available
- *    < 0  if  client should be terminated
- *
- *    The request returned must be contiguous so that it can be
- *    cast in the dispatcher to the correct request type.  Because requests
- *    are variable length, ReadRequestFromClient() must look at the first 4
- *    or 8 bytes of a request to determine the length (the request length is
- *    in the 3rd and 4th bytes of the request unless it is a Big Request
- *    (see the Big Request Extension), in which case the 3rd and 4th bytes
- *    are zero and the following 4 bytes are the request length.
- *
- *    Note: in order to make the server scheduler (WaitForSomething())
- *    "fair", the ClientsWithInput mask is used.  This mask tells which
- *    clients have FULL requests left in their buffers.  Clients with
- *    partial requests require a read.  Basically, client buffers
- *    are drained before select() is called again.  But, we can't keep
- *    reading from a client that is sending buckets of data (or has
- *    a partial request) because others clients need to be scheduled.

+ * ReadRequestFromClient

+ *    Returns one request in client->requestBuffer.  The request

+ *

+ *    > 0  if  successful, specifies length in bytes of the request

+ *    = 0  if  entire request is not yet available

+ *    < 0  if  client should be terminated

+ *

+ *    The request returned must be contiguous so that it can be

+ *    cast in the dispatcher to the correct request type.  Because requests

+ *    are variable length, ReadRequestFromClient() must look at the first 4

+ *    or 8 bytes of a request to determine the length (the request length is

+ *    in the 3rd and 4th bytes of the request unless it is a Big Request

+ *    (see the Big Request Extension), in which case the 3rd and 4th bytes

+ *    are zero and the following 4 bytes are the request length.

+ *

+ *    Note: in order to make the server scheduler (WaitForSomething())

+ *    "fair", the ClientsWithInput mask is used.  This mask tells which

+ *    clients have FULL requests left in their buffers.  Clients with

+ *    partial requests require a read.  Basically, client buffers

+ *    are drained before select() is called again.  But, we can't keep
