In order to call a C function from C++ code, you would use the “extern “C”” keyword when declaring the function in C. Then, you would call the function just like you would call any other function. An example will help clarify this: /*this is what the C++ code would look like for the declaration of the foo function, which is defined somewhere else in C code: */ extern "C" void foo( ); And then to call the function in the C++ code, it would look like this: //the declaration: extern "C" void foo(); void main() { // the function call: foo( ); } read less
