91.生成ini文件并写入和读取ini文件

• 写入

WritePrivateProfileStringA("hello money", infx[i].name, money, "1.ini");

• 按照字符串读取

  GetPrivateProfileStringA("hello money", infx[i].name, "NULL", money, 40, "1.ini");

  函数原型:

  GetPrivateProfileStringA(
              _In_opt_ LPCSTR lpAppName,
              _In_opt_ LPCSTR lpKeyName,
              _In_opt_ LPCSTR lpDefault,
              _Out_writes_to_opt_(nSize, return +1) LPSTR lpReturnedString,
              _In_     DWORD nSize,
              _In_opt_ LPCSTR lpFileName
              );

  GetPrivateProfileIntA(
              _In_     LPCSTR lpAppName,
              _In_     LPCSTR lpKeyName,
              _In_     INT nDefault,
              _In_opt_ LPCSTR lpFileName
              );

  按照int类型读取,结果在返回值

  int  num=0;
  num=GetPrivateProfileIntA("hello money", infx[i].name, num, "1.ini");//结果在返回值
