C/C++ and Assembly Language Interface

C++ Programming Examples

This section shows examples of the features specific to C++. These exam-
ples are:
• "Using Fract Type Support" on page 1-176
• "Using Complex Number Support" on page 1-177
By default, the
C++ mode, use the corresponding option on the command line, or select
the option in the Project Options dialog box in the VisualDSP++
environment.
For example, the following command line
cc219x -c++ source.cpp -proc ADSP-2191
runs with:
cc219x
-c++
Specifies that the following source file is written in ANSI/ISO
standard C++ extended with the Analog Devices keywords.
source.cpp
Specifies the source file for your program.
-proc ADSP-2191
Specifies that the compiler should produce code suitable for the
ADSP-2191 DSP.
