ini文件读入思考 GetPrivateProfileString( )

[yunsongblue]

有如下形式的ini文件，如何编写才能读出相应的键名所对应的值?

[b][节1]
键名集合的名称=键名1|键名2|键名3
键所对应值集合的名称=键名1的值|键名2的值|键名3的值[/b]

GetPrivateProfileString( )
搜索的格式是
[节1]
键名1=键名1的值
怎么编写才能变成这种，当读键名1时取键名1的值，当读键名2时取键名2的值，当读键名3时取键名3的值
[节1]
键名集合的名称=键名1|键名2|键名3
键所对应值集合的名称=键名1的值|键名2的值|键名3的值

DWORD WINAPI GetPrivateProfileString( _In_ LPCTSTR lpAppName, _In_ LPCTSTR lpKeyName, _In_ LPCTSTR lpDefault, _Out_ LPTSTR lpReturnedString, _In_ DWORD nSize, _In_ LPCTSTR lpFileName ); GetPrivateProfileString function Retrieves a string from the specified section in an initialization file. Note This function is provided only for compatibility with 16-bit Windows-based applications. Applications should store initialization information in the registry. Syntax C++ DWORD WINAPI GetPrivateProfileString( _In_ LPCTSTR lpAppName, _In_ LPCTSTR lpKeyName, _In_ LPCTSTR lpDefault, _Out_ LPTSTR lpReturnedString, _In_ DWORD nSize, _In_ LPCTSTR lpFileName ); Parameters lpAppName [in] The name of the section containing the key name. If this parameter is NULL, the GetPrivateProfileString function copies all section names in the file to the supplied buffer. lpKeyName [in] The name of the key whose associated string is to be retrieved. If this parameter is NULL, all key names in the section specified by the lpAppName parameter are copied to the buffer specified by the lpReturnedString parameter. lpDefault [in] A default string. If the lpKeyName key cannot be found in the initialization file, GetPrivateProfileString copies the default string to the lpReturnedString buffer. If this parameter is NULL, the default is an empty string, "". Avoid specifying a default string with trailing blank characters. The function inserts a null character in the lpReturnedString buffer to strip any trailing blanks. lpReturnedString [out] A pointer to the buffer that receives the retrieved string. nSize [in] The size of the buffer pointed to by the lpReturnedString parameter, in characters. lpFileName [in] The name of the initialization file. If this parameter does not contain a full path to the file, the system searches for the file in the Windows directory. 第二个参数不就是键名，填入你想要读取的键名1/2/3？？？？
