 * Many of the DIMSE routines take parameters for a blocking mode
 * and a timeout.  In all cases, these parameters are only used
 * when receiving commands or data sets (reading).  There are no blocking
 * and timeout options for send operations.
 * When receiving commands or data sets:
 * If the parameter blockMode is DIMSE_BLOCKING, the DIMSE routine
 * will wait until a response arrives before returning.
 * If the parameter blockMode is DIMSE_NONBLOCKING then the DIMSE routine
 * will wait at most timeout seconds for a response and if no response arrives
 * will return DIMSE_NODATAAVAILABLE.  In both cases waiting will be
 * interrupted by association release, and abort messages, or network
 * disruption.
