c/c++动态调用dll中的函数方法

//调用前，需讲dll文件放在项目文件中 #include #include int main( int argc, char *argv[] ) {

#include
#include
int main( int argc, char *argv[] )
{

    HINSTANCE hdll = NULL;
    hdll = LoadLibrary ( "Mwic_32.dll" );
//通过类型定义语句typedef来定义函数指针类型
    typedef BOOL ( _stdcall *lpFileEncrypt )( INT, INT);
//函数声明
    lpFileEncrypt FileEncrypt1;
//获取函数File Encrypt的函数指针
    FileEncrypt1 = ( lpFileEncrypt )::GetProcAddress( hdll, "auto_init" );
//调用DLL中函数auto_init
    int a = FileEncrypt1(0,38400);
//释放DLL模块
    FreeLibrary( hdll );
    char * aa;
    printf( "Result= %d\n", a);
    system("PAUSE");
