Using Header Files With VERSION3

Specify the names of the VERSION3 Standard C++ Library header files as defined in

the standard. On NonStop systems, header files have been renamed in some cases to

implement the three versions of the library, but in all cases you need only to specify the

standard names.

To use a VERSION3 header file, do not include .h (even if the standard name contains

.h).

For example, you can specify:

#include <new>

But you cannot specify:

#include <new.h>

Logic has been built into the header files to redirect your calls to the version of the

library you are using. For example, if you are using VERSION2 and you specify:

#include <exception>

logic in the header files redirects you to the VERSION2 header file, which is actually

named EXCEPTION2 (OSS and Windows) or EXCEPTI2 (Guardian). You can see

these alternate header file names in your program listing, but your include command

should specify only the standard name, such as exception in this example.

Installation Notes for VERSION2

The Standard C++ Library is delivered on the site update tape (SUT) for a NonStop

system. On the PC, the Standard C++ Library is installed with the HP Enterprise Toolkit

(ETK) or the Tandem Development Suite (TDS). No installation is required by the user.

Table 5-3 summarizes where the parts of the VERSION2 Standard C++ Library are

installed in the different environments (Guardian environment, OSS environment, and

PC running Windows).
