GRASS and C++

(page to be expanded)

Calling GRASS library functionality in C++

For working examples, see:

I/O:

• lib/iostream/

Raster data processing

• raster/r.terraflow/

Image processing

• imagery/i.atcorr/

Visualization:

• visualization/xganim/
• visualization/wximgview/

Notes

When developing C++ code to call a C function you need to specified for the compiler that the gis.h include is C code with:

extern "C" 
{
#include <grass/gis.h>
}
