ini檔案在儲存軟體的配置資訊方面有著良好的作用，為了適應跨平台的功能，我們必須放棄微軟的相關api，自己實現乙個ini的檔案讀寫操作類。 下面我給出該類的具體實現。我的email是
（一） 標頭檔案 h
//ini檔案 以";"表示注釋行
class cinifile ;
（二） 實現檔案 cpp
static const int q_ini_size = 0x4000;
cinifile::cinifile(const char* filename)
}cinifile::~cinifile()
void cinifile::load(const char* filename)
void cinifile::clearcontents()
}bool cinifile::load_ini_buf(char* buf,int *len)
buf[i] = '/0';
*len = i;
ret = true; }
fclose(f); }
return ret; }
bool cinifile::parse_ini_buf(const char* buf,const char* section,const char* key,
int *s_0,int *s_1,int *k_0,int *k_1,int *v_0,int *v_1)
while( p[i] !=']' && p[i] != '/0');
if (strncmp(p+s_i,section,i-s_i)==0 && strlen(section) ==(i-s_i) )
*s_0 = s_i;
*s_1 = i;
//section symbol end
while ((p[i] != '/0') && !(p[i] =='[' && (p[i-1] == '/r' || p[i-1] == '/n')) )//new line end
m = t;
if (p[m] != ';' || ( (m < i - 1) && p[m] != '/' && p[m+1] !='/' ))//skip comment
} f_not_find:
if (def_value != null)
strncpy(value,def_value,len);
f_exit:
return ret; }
char* cinifile::readstring(const char* section,const char* key,const char* def_value) ;
readstr(section,key,geo_kd_buf,1024,def_value);
return geo_kd_buf; }
int cinifile::readint(const char* section,const char* key,const int def_value);
if (!readstr(section,key,v,sizeof(v),null))
return def_value;
else return atoi(v); }
double cinifile::readfloat(const char* section, const char* key,const double def_value);
if (!readstr(section,key,v,sizeof(v),null))
return def_value;
else return atof(v); }
bool cinifile::readbool(const char* section,const char* key,const bool def_value);
if (!readstr(section,key,v,sizeof(v),null))
return def_value;
else ; }
bool cinifile::writestring(const char* section,const char* key,const char* value);
char m_buf[q_ini_size]=;
int vlen = strlen(value);
bool ret = false;
if (section!= null && key != null && value !=null)
else
}else if (k_0 == -1) //section exist and key not exist
else
file *f = fopen(m_filename,"w");
if (f != null)
fclose(f); }
ret = true; }
f_exit:
return ret; }
bool cinifile::writeint(const char* section,const char* key,const int value);
sprintf(v,"%d",value);
return writestring(section,key,v); }
bool cinifile::writefloat(const char* section,const char* key,const double value);
sprintf(v,"%f",value);
return writestring(section,key,v); }
bool cinifile::writebool(const char* section,const char* key,const bool value);
if (value==true)
else memcpy(v,"false",5);
return writestring(section,key,v); }
void cinifile::erasesection(const char* section);
char m_buf[q_ini_size]=;
if (section!= null)
fclose(f); }
} }f_exit:
return; }
使用方法：
cinifile* ini = new cinifile("d://wxy3064.ini");
或者 cinifile* ini = new cinifile();
ini ->load("d://wxy3064.ini");
ini->writestring("coltheme","type","gsm");
ini->writeint("coltheme","value",3);
delete ini;
