About This Manual
The Open System Services Porting Guide describes how to port applications written in
the C and C++ languages to the Open System Services (OSS) environment. The
emphasis is on moving applications from the UNIX environment to the OSS
environment. Migrating applications from the Guardian environment to the OSS
environment is also covered. This guide includes information about:
•
Porting ISO/ANSI C and C++ programs to Open System Services
•
Porting Common C programs to Open System Services
•
Modifying make files for OSS
•
Compiling C and C++ programs in the OSS environment
•
Guidelines for using standard application program interfaces (APIs)
•
Guidelines for using OSS API extensions
•
Guidelines for using Guardian procedure calls
•
Differences between the OSS API and standard APIs
•
Interoperability between Guardian and OSS execution environments
•
Interoperability between Guardian and OSS user environments
•
Some useful porting tools
•
Performance considerations
•
Migration considerations for the TNS/R and TNS/E native environments
•
Porting threaded applications to Standard POSIX Threads
Audience
The Open System Services Porting Guide is intended for application programmers who
are migrating C-language and C++-language applications written for other UNIX
platforms (or for the Guardian environment) to the OSS environment, or for those
writing new C or C++ applications for the OSS environment.
