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:

Pro*C/C++ Programmer's Guide for additional informationThe 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.
Pro*C/C++ supports the following features:
Remote access with Oracle Net Services or local access to Oracle databases
Embedded PL/SQL blocks
Bundled database calls, which can provide better performance in client/server environments
PL/SQL version 9.0 and host language arrays in PL/SQL procedures
Multi-threaded applications
Can be deployed in Instant Client environments. For more information, refer to the OCI Instant Client documentation.
Microsoft Visual C++ support, version 6.0 for 32-bit applications
Note:
Borland C++ is no longer supported.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.

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