This section describes the language extensions to the ISO/ANSI C standard that are
supported by the HP native C and C++ compilers, the TNS C compiler, and the TNS
C++ preprocessor.
Keywords
A keyword is a word symbol that has a special predefined syntactic or semantic
meaning in a programming language. Table 2-1 lists the reserved keywords that HP
has added as extensions to the C and C++ languages. Table 2-1 notes whether there
are differences between using the keyword in the native or TNS environment.
Native C and C++ treat these HP extensions as keywords only if the EXTENSIONS
pragma is in effect. This feature allows you to choose to compile a program so that
standards conformance is enforced. This feature also ensures the acceptance of a
