how to call .lib functions that i created in c++ in nasm

i have .lib file that i created in c++ with several functions.

_declspec(dllexport) int atoi_new(char * c , int len){

    int ar = 0;
    int f = 0;

    for(int i = 0 ; i < len ; i++){

            f *= 10;
            ar  = (int) c[i];
            ar -= 0x30;
            f += ar ;
            }
        return f;
    };

this maybe not a good example but you get the idea . know i want to use this function from .lib file in nasm any idea how to do this ?

You should declare the functions as C, otherwise the names get mangled and you would have to look it up, what name the compiler made up.

#ifdef __cplusplus
extern "C" {
#endif

_declspec(dllexport) int atoi_new(char * c , int len);

#ifdef __cplusplus
}
#endif

or

extern "C"  _declspec(dllexport) int atoi_new(char * c , int len);
