1 Introducing Pro*C/C++

This chapter describes Pro*C/C++, the Oracle programmatic interface for the C and C++ languages running on Windows operating systems. Pro*C/C++ enables you to build Oracle database applications in a Win32 environment.

This chapter contains these topics:

What Is Pro*C/C++?

The Pro*C/C++ precompiler enables you to create applications that access your Oracle database whenever rapid development and compatibility with other systems are your priorities.

The Pro*C/C++ programming tool enables you to embed Structured Query Language (SQL) statements in a C or C++ program. The Pro*C/C++ precompiler translates these statements into standard Oracle runtime library calls, then generates a modified source program that you can compile, link, and run in the usual way.

Features

Pro*C/C++ supports the following features:

Restrictions

Pro*C/C++ does not support 16-bit code generation.

Directory Structure

Installing Oracle software creates a directory structure on your hard drive for the Oracle products. A main Oracle directory contains the Oracle subdirectories and files that are necessary to run Pro*C/C++.

When you install Pro*C/C++, Oracle Universal Installer creates a directory called \precomp in the ORACLE_BASE\ORACLE_HOME directory. This subdirectory contains the Pro*C/C++ executable files, library files, and sample programs listed in Table 1-1.

Table 1-1 precomp Directory Structure

Directory Name Contents

\admin

Configuration files

\demo\proc

Sample programs for Pro*C/C++

\demo\sql

SQL scripts for sample programs

\doc\proc

Readme files for Pro*C/C++

\help\proc

Help files for Pro*C/C++

\lib\msvc

Library files for Pro*C/C++

\mesg

Message files

\misc\proc

\public

Header files


Note:

The \precomp directory can contain files for other products, such as Pro*COBOL.

Known Problems, Restrictions, and Workarounds

Although all Windows operating systems allow spaces in file names and directory names, the Oracle Pro*C/C++ and Oracle Pro*COBOL precompilers will not precompile files that include spaces in the filename or directory name. For example, do not use the following formats:

  • proc iname=test one.pc

  • proc iname=d:\dir1\second dir\sample1.pc
