急用！Linux环境下，使用C语言读写ini文件。

[FigoZhu]

急用，最好有完整的代码。
谢谢！

[sewenew]

从我见过的ini文件来看，都是文本方式的（不知道是不是我见的太少了，不要嘲笑阿，呵呵），如果你的ini文件时文本方式的，那么直接用和文件相关的函数读写，移动指针不就可以了吗？

在Linux下使用的与window下的GetPrivateProfileInt和GetPrivateProfileString相同的函数，free software :-)

GetPrivateProfileInt和GetPrivateProfileString函数。

[code_tin]

ugg阿。人家是要在linux环境下呢。。。

[FigoZhu]

To chenhu_doc,

兄弟，只写了读啊。
写怎么办啊？

[Dong]

int ReadIniFileColumn(char* szFileName, char* szColumnName, char* szColumnValue, char* szDefaultValue);
------------------------以下是定义，相干宏改动一下，看看就知道
int ReadIniFileColumn(char* szFileName, char* szColumnName, char* szColumnValue, char* szDefaultValue)
{
FILE* IniFile = NULL;
struct stat buf;
if(stat(szFileName, &buf))
return ERR_FILE_NOT_EXIST;
IniFile = fopen(szFileName, "r");
if(!IniFile)
return ERR_FILE_ACCESS;
char str[256];
char column[256];
char value[256];
memset(str, 0, 256);
while(fgets(str, 256, IniFile) != NULL)
{
if(str[0] == '#')
continue;
if(!strstr(str, szColumnName))
continue;
RemoveStrChr(str, str, ' ');
RemoveStrChr(str, str, '\t');
RemoveStrChr(str, str, '\n');
char* tmp = str;
while(*tmp != 0 && *tmp != '#')
++tmp;
tmp = 0;
if((tmp = strchr(str, '=')) == NULL)
continue;
memset(column, 0, 256);
memset(value, 0, 256);
strncpy(column, str, tmp - str);
column[tmp - str] = 0;
sprintf(value, "%s", ++tmp);
//sscanf(str,"%s=%s",column,value);
if(!strcmp(szColumnName, column))
{
sprintf(szColumnValue, "%s", value);
fclose(IniFile);
return SUCCESS;
}
memset(str, 0, 256);
}
fclose(IniFile);
sprintf(szColumnValue, "%s", szDefaultValue);
return SUCCESS;
}
-------------------------------------------
以下是要读取的ini文件

#####LOG FILE PATH (direction!!)#######
LOGFILE=/home/oracle/wangds/atm_server/log
#####LISTEN PORT#######################
PORT=8100
##########FTPPath#####################
FTPPATH=/home/oracle/ftpdir
##还可以是这样的
FILE=/home/iniFile#########这也可以，反正'#'表示注解

[Dong]

上面的程序，最初是在一个大公司工作的时候写的。

[zez]

简单的,自己 fopen,seek,gets,read 等等..
不嫌麻烦的话,去 sf下个开源的ini解析包

[Dong]

RemoveStrChr(str, str, ' ');
RemoveStrChr(str, str, '\t');
RemoveStrChr(str, str, '\n');
---------------------------------
这里用到了这个函数的代码是这样的

int RemoveStrChr(char* szSource, char* szDest, char Chr)
{
if(szSource < 0)
return FAIL;
while(*szSource != 0)
{
if(*szSource == Chr)
{
++szSource;
continue;
}
*szDest++ = *szSource++;
}
*szDest = 0;
return SUCCESS;
}

记得先分配好空间
