Hi Yamin, The consequences of declaring a function as extern "C" are... 1) the name will be mangled according to your platform's C mangling convention*. 2) I recall (and I may be mistaken) that such a function acts as a "C barrier", and thus exceptions do not propagate through such a function. Merely specifying the header declaration (prototype) as an extern "C" is good enough for the translation unit's definition (implementation) to use the C specification. HTH, --Eljay * some C mangling conventions (depending on platform)... 1) convert to uppercase (ala Pascal) 2) prefix a leading underscore 3) leave the identifier as given.
