c語言ini文件讀寫
⑴ ini、配置文件、讀取鍵值，源代碼（C/C++),謝謝
1,c++ builder 用法：
#include <vcl.h>
TIniFile *GameIni = new TIniFile ("d:\\murong.ini");
AnsiString value;
value = GameIni->ReadString("Section2 Name", "KeyName2","");
delete GameIni;
2，VC
char value[20];
GetPrivateProfileString("Section2 Name","KeyName2",NULL,value,20,"d:\\murong.ini");
⑵ INI的文件讀寫
讀取 (_In_LPCTSTRlpAppName,_In_LPCTSTRlpKeyName,_In_LPCTSTRlpDefault,_Out_LPTSTRlpReturnedString,_In_DWORDnSize,_In_LPCTSTRlpFileName);參數說明：
lpAppName （輸入參數）節名
lpKeyName （輸入參數）鍵名
lpDefault （輸入參數）默認值。INI讀取失敗時，得到這個值
lpReturnedString （輸出參數）讀取到的鍵值
nSize （輸入參數）lpReturnedString的緩沖區大小
lpFileName （輸入參數）INI文件的文件路徑
返回值：
讀取到的字元數，不包括末尾的' '字元或L' '字元。
寫入 (_In_LPCTSTRlpAppName,_In_LPCTSTRlpKeyName,_In_LPCTSTRlpString,_In_LPCTSTRlpFileName);參數說明：
lpAppName （輸入參數）節名
lpKeyName （輸入參數）鍵名
lpString （輸入參數）需要寫入的鍵值
lpFileName （輸入參數）INI文件的文件路徑
返回值：
寫入成功返回非零值，寫入失敗返回零值，可以用GetLastError函數得到錯誤原因。 #!/usr/bin/envpython#-*-coding:UTF-8-*-importConfigParseriniparser=ConfigParser.ConfigParser()#初始化一個INI讀寫類的對象iniparser.read('filename.ini')#讀取INI文件key_value=iniparser.get('section_name_1','key_name')#解析INI文件printkey_value#生成INI文件iniparser.add_section('section_name_2')iniparser.set('section_name_2','key_name','key_value')withopen('filename.ini','w')asinifile: iniparser.write(inifile)#寫入INI文件
