::GetPrivateProfileString 读取 INI 文件的整个部分
我正在修改现有的 C++ 应用程序并移出一些当前硬编码的值。
我正在使用一个类来执行此操作，该类将“管理”整个事情并保存 INI 文件中的值的 map 。
现在我必须使用 ::GetPrivateProfileString 函数单独读取每个值 - 我可以以某种方式读取整个部分而不是单个值吗？
不想手动读取文件，但如果有任何合理（即高效+易于使用）的现有方式，我愿意寻求建议。
编辑：刚才必须“真正”使用它，解决方案确实是将 NULL 作为 lpKeyName 值传递。包括解析返回值的完整代码：
char buffer[MAX_STRING_SIZE];
int charsCount = ::GetPrivateProfileString("MySection", NULL, NULL, buffer, MAX_STRING_SIZE, m_strIniPath);
CString curValue;
curValue.Empty();
char curChar = '\0';
for (int i = 0; i < charsCount; i++)
{
curChar = buffer[i];
if (curChar == '\0')
{
if (curValue.GetLength() > 0)
HandleValue(curValue);
curValue.Empty();
}
else
{
curValue.AppendFormat("%c", curChar);
}
}
if (curValue.GetLength() > 0)
HandleValue(curValue);
这并不简单，因为它返回由零字符（EOS？）分隔的键，因此我必须使用如上所述的循环来提取它们 - 为了每个可能需要它的人而在此处共享它。 :-)
I'm modifying existing C++ application and moving out some values that are currently hard coded.
I'm doing this with one class that will "manage" this whole thing and hold map<CString, CString> of the values from the INI file.
Right now I have to read each value separately using ::GetPrivateProfileString function - can I somehow read whole section instead of single value?
Prefer not to have to read the file manually, but if there's any reasonable (i.e. efficient + simple to use) existing way I'm open for suggestions.
Edit: just now had to use it "for real" and the solution was indeed passing NULL as the lpKeyName value. Complete code including parsing the return value:
char buffer[MAX_STRING_SIZE];
int charsCount = ::GetPrivateProfileString("MySection", NULL, NULL, buffer, MAX_STRING_SIZE, m_strIniPath);
CString curValue;
curValue.Empty();
char curChar = '\0';
for (int i = 0; i < charsCount; i++)
{
curChar = buffer[i];
if (curChar == '\0')
{
if (curValue.GetLength() > 0)
HandleValue(curValue);
curValue.Empty();
}
else
{
curValue.AppendFormat("%c", curChar);
}
}
if (curValue.GetLength() > 0)
HandleValue(curValue);
It's not trivial as it returns the keys separated by zero character (EOS?) so I had to extract them using loop such as the above - share it here for the sake of everyone who might need it. :-)

您不需要手动阅读该文件，但阅读
You don't need to read the file manually but it helps to read the manual for GetPrivateProfileString:
您可能应该考虑使用 Boost.PropertyTree （它提供了 INI 解析器）：
You should probably consider the use of Boost.PropertyTree (which provides a INI parser) :
