This chapter describes how you can use the Pro*C/C++ Precompiler to precompile your C++ embedded SQL application, and how Pro*C/C++ generates C++ compatible code. This chapter contains the following topics:
Understanding C++ Support
To understand how Pro*C/C++ supports C++, you must understand the basic functional capabilities of Pro*C/C++. In particular, you must be aware of how Pro*C/C++ differs from Pro*C Version 1.
The basic capabilities of Pro*C/C++ are:
To support its C preprocessor capabilities and to enable host variables to be declared outside a special Declare Section, Pro*C/C++ incorporates a complete C parser. The Pro*C/C++ parser is a C parser; it cannot parse C++ code.
This means that for C++ support, you must be able to disable the C parser, or at least partially disable it. To disable the C parser, the Pro*C/C++ Precompiler includes command-line options to give you control over the extent of C parsing that Pro*C/C++ performs on your source code.

No Special Macro Processing
Bootcamp mac update. Using C++ with Pro*C/C++ does not require any special preprocessing or special macro processors that are external to Pro*C/C++. There is no need to run a macro processor on the output of the precompiler to achieve C++ compatibility.
If you are a user of a release of Pro*C/C++ Precompiler before this one, and you did use macro processors on the precompiler output, you should be able to precompile your C++ applications using Pro*C/C++ with no changes to your code.
Precompiling for C++
To control precompilation so that it accommodates C++, there are four considerations:
Code Generation
You must be able to specify what kind of code, C compatible code or C++ compatible code, the precompiler generates. Pro*C/C++ by default generates C code. C++ is not a perfect superset of C. Some changes are required in generated code so that it can be compiled by a C++ compiler.
For example, in addition to emitting your application code, the precompiler interposes calls to its runtime library, SQLLIB. The functions in SQLLIB are C functions. There is no special C++ version of SQLLIB. For this reason, if you want to compile the generated code using a C++ compiler, Pro*C/C++ must declare the functions called in SQLLIB as C functions.
For C output, the precompiler would generate a prototype such as
But for C++ compatible code, the precompiler must generate
You control the kind of code Pro*C/C++ generates using the precompiler option CODE. There are three values for this option: CPP, KR_C, and ANSI_C. The differences between these options can be illustrated by considering how the declaration of the SQLLIB function sqlora differs among the three values for the CODE option:
When you specify CODE=CPP, the precompiler
Parsing Code
You must be able to control the effect of the Pro*C/C++ C parser on your code. You do this by using the PARSE precompiler option, which controls how the precompiler's C parser treats your code.
The values and effects of the PARSE option are:
Table 12-1 Values and Effects of the PARSE Option
This option value is the default if the value of the CODE option is anything other than CPP. It is an error to specify PARSE=FULL when CODE=CPP.
To generate C++ compatible code, the PARSE option must be either NONE or PARTIAL. If PARSE=FULL, the C parser runs, and it does not understand C++ constructs in your code, such as classes.
Output Filename Extension
Most C compilers expect a default extension of '.c' for their input files. Different C++ compilers, however, can expect different filename extensions. The CPP_SUFFIX option provides the ability to specify the filename extension that the precompiler generates. The value of this option is a string, without the quotes or the period. For example, CPP_SUFFIX=cc, or CPP_SUFFIX=C.
System Header Files
Pro*C/C++ searches for standard system header files, such as
stdio.h , in standard locations that are platform specific. Pro*C/C++ does not search for header files with extensions such as hpp or h ++. For example, on almost all UNIX systems, the file stdio.h has the full path name /usr/include/stdio.h .
But a C++ compiler has its own version of
stdio.h that is not in the standard system location. When you are precompiling for C++, you must use the SYS_INCLUDE precompiler option to specify the directory paths that Pro*C/C++ searches to look for system header files. For example:
Use the INCLUDE precompiler option to specify the location of non-system header files. The directories specified by the SYS_INCLUDE option are searched before directories specified by the INCLUDE option. See also: 'INCLUDE'.
If PARSE=NONE, the values specified in SYS_INCLUDE and INCLUDE for system files are not relevant, since there is no need for Pro*C/C++ to include system header files. (You can, of course, still include Pro*C/C++-specific headers, such
sqlca.h , using the EXEC SQL INCLUDE statement.)
Example Programs
This section includes three example Pro*C/C++ programs that include C++ constructs. Each of these programs is available on-line, in your
demo directory.
