OpenVMS VAXCXXL01_062 VAX V6.1 DEC C++ Class RTL ECO Summary

 
NOTE:  An OpenVMS saveset or PCSI installation file is stored
       on the Internet in a self-expanding compressed file.
       The name of the compressed file will be kit_name-dcx_vaxexe
       for OpenVMS VAX or kit_name-dcx_axpexe for OpenVMS Alpha.
 
       Once the file is copied to your system, it can be expanded
       by typing RUN compressed_file.  The resultant file will
       be the OpenVMS saveset or PCSI installation file which
       can be used to install the ECO.

ECO KIT SUMMARY:

An ECO kit exists for DEC C++ Class Run Time Libraries on OpenVMS
VAX V6.1.  This kit addresses the following problems: 


Problems addressed in VAXCXXL01_062 kit

   o  When the Complex Library exp() function  detects  an  underflow
      error,  the  resulting  value  is  now  (0,0)  instead  of (+/-
      max-float, +/- max-float).


   o  The division routines within  the  Complex  Library  now  catch
      divide-by-zero errors instead of signalling them.


   o  The String extraction operator now takes  care  of  dynamically
      allocating the String to accommodate the input.


   o  When you open a file specifying ios::ate but  not  ios::app  to
      the  filebuf  open()function,  the  file is no longer opened in
      O_APPEND mode.  This incorrect behavior caused all data  to  be
      written  to the end of the file, regardless of the current file
      position.


INSTALLATION NOTES:

The system does not need to be rebooted after this kit is installed.
However, if you have other nodes in your OpenVMS VAXcluster, they 
should be rebooted or you should install this kit on each system
in order to make use of the new image(s).
