c语言ini文件读写
⑴ ini、配置文件、读取键值，源代码（C/C++),谢谢
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的文件读写
读取 (_In_LPCTSTRlpAppName,_In_LPCTSTRlpKeyName,_In_LPCTSTRlpDefault,_Out_LPTSTRlpReturnedString,_In_DWORDnSize,_In_LPCTSTRlpFileName);参数说明：
lpAppName （输入参数）节名
lpKeyName （输入参数）键名
lpDefault （输入参数）默认值。INI读取失败时，得到这个值
lpReturnedString （输出参数）读取到的键值
nSize （输入参数）lpReturnedString的缓冲区大小
lpFileName （输入参数）INI文件的文件路径
返回值：
读取到的字符数，不包括末尾的' '字符或L' '字符。
写入 (_In_LPCTSTRlpAppName,_In_LPCTSTRlpKeyName,_In_LPCTSTRlpString,_In_LPCTSTRlpFileName);参数说明：
lpAppName （输入参数）节名
lpKeyName （输入参数）键名
lpString （输入参数）需要写入的键值
lpFileName （输入参数）INI文件的文件路径
返回值：
写入成功返回非零值，写入失败返回零值，可以用GetLastError函数得到错误原因。 #!/usr/bin/envpython#-*-coding:UTF-8-*-importConfigParseriniparser=ConfigParser.ConfigParser()#初始化一个INI读写类的对象iniparser.read('filename.ini')#读取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)#写入INI文件
