We already have a few C-callable wrappers; they are in ImfCRgbaFile.h:


typedef unsigned short ImfHalf;

void    ImfFloatToHalf (float f,
                        ImfHalf *h);

void    ImfFloatToHalfArray (int n,
                             const float f[/*n*/],
                             ImfHalf h[/*n*/]);

float   ImfHalfToFloat (ImfHalf h);

void    ImfHalfToFloatArray (int n,
                             const ImfHalf h[/*n*/],
                             float f[/*n*/]);
