  7. Компилятор gcc, платформа LINUX Компоновка библиотеки: double a=3.1415; int sh_fun(int i){ return i*i; } //gcc -shared -fPIC 1d.c -o lib1d.so Явное связывание: #include<stdio.h> #include<stdlib.h> #include<dlfcn.h> typedefint (*fun)(int); externdouble a; int main(int argc, char* argv[]){ fun f; printf("Dynamic library test\n"); void* h=dlopen("lib1d.so",RTLD_LAZY); printf("%g\n",a); f=(fun)dlsym(h,"sh_fun"); printf("%i\n", f(5)); //int (*f)(int)=dlsym(h,"sh_fun"); //printf("%i\n", (*f)(3)); dlclose(h); return 0; } //gcc 2.c -L. -l1d -ldl -o 2 //3.1415 //25 Неявное связывание: #include<stdio.h> #include<stdlib.h> externdouble a; int sh_fun(int); int main(int argc, char* argv[]){ if(argc>1) a=atof(argv[1]); printf("%g\n",a); printf("%i\n", sh_fun(3)); return 0; } //gcc 1.c -L. -l1d -o 1 //3.1415 //9

  8. Компилятор cl (Microsoft VS) Компоновка библиотеки: #include<windows.h> extern__declspec(dllexport) int a=23; __declspec(dllexport) int f(int b){ return b*b; } __declspec(dllexport) int g(int b){ return b*b*b; } BOOL WINAPI DllMain(HANDLE hModule, DWORD dwReason, LPVOID lpReserved){ return TRUE; } //cl /c td1.c //link /DLL td1.obj

  9. Компоновка библиотеки с помощью .def-файла: #include<windows.h> int a=29; int f(int b){ return b*b*b; } int g(int b){ return b*b*b*b; } BOOL WINAPI DllMain(HANDLE hModule, DWORD dwReason, LPVOID lpReserved){ return TRUE; } //cl /c td2.c //link /DLL /DEF:td2.def td2.obj LIBRARY td2 EXPORTS a @1 f @2 g @3

  10. Явное связывание: Неявное связывание: #include<windows.h> extern__declspec(dllimport) int a; int f(int); int g(int); int main(){ printf("%i %i %i\n",a,f(3),g(3)); return 0; } //cl t1.c td1.lib #include<windows.h> typedefint (*fun)(int); int main(){ HINSTANCE hInst; fun pf,pg; int* pa; hInst=LoadLibrary("td2.dll");//("td1.dll"); pa=(int*)GetProcAddress(hInst, "a"); pf=(fun)GetProcAddress(hInst, "f"); pg=(fun)GetProcAddress(hInst, "g"); printf("%i %i %i\n",*pa,pf(3),pg(3)); FreeLibrary(hInst); return 0; } //cl t2.c kernel32.lib
