4007.0. "Iconic Map Buffer ???" by LFOIS1::ALIE () Mon Nov 02 1992 11:45

    Hello,
    
    one of our customer has DECMCC 1.2 on ultrix 4.2, and developp is own
    access module "UNIX"
    
    The goal is to monitor the Unix process and disk.
    
    On FCL prompt when they did : FCL> show unix dogger all
    
    				  FCL> they receive about 70 item an
    					everything is OK
    
    
    On Iconic Map, for the same command:
    				the receive a handle "more.."
    
    				and they cannot receive the data
    
    				IS there a buffer to show data ???
    				
    PS: WITH 3 item we have no pb either on FCL or Iconic Map.
    
    
    Thanks for your help.

The Iconic Map issues a show call function and we include an outp parameter  
which is an MCC Descriptor with a buffer.  The output data is returned in
ILV-encoded form by your access module.
  

My guess is that a CVR of MCC_S_INSUF_BUF is returned (output data buffer too
small). With this, the access module code must set the handle to more and outp 
Descriptor must have mcc_w_curlen set to the value needed.  If this is the case,
the Iconic Map creates a new MCC Descriptor with the correct size buffer (which
cannot exceed 20K) and re-issues the call.

I believe the FCL may use dynamic vs static descriptors.

Hope this helps.

    fcl now (v1.2) uses a dynamic buffer, so these problems no longer
    exist from its stand point.
