C api

Hi,

I am new to Lotus .

Was trying to learn C API.

But I seem to be getting errors in the header file when i try to run even a basic program which has just the inclusion of the header files

#include<nsfdata.h>

int main(){return 0}

I am runnin this on C++ compiler.

i have Downloaded the 8.0 C API toolkit as well as the C++ API toolkit.

Both packages give me the same errors.

How do i proceed?
