自从大学学完C之后，就再也没用过它了，

在网上找代码，七拼八凑之后，终于成形~~勉强能用，不喜勿喷，^_^！

int GetValue(const wchar_t *key, wchar_t *value){    FILE* fpcfg = NULL;    wchar_t var[256], val[256];//key,value    wchar_t linebuf[1024];    wchar_t* ptr1 = NULL;    wchar_t* ptr2 = NULL;    wchar_t* delimiter = NULL;    int k = 0;    assert(key != NULL && value != NULL);    //testConfig.ini中的内容为：    //key1 = value1    //key2 = value2    fpcfg = fopen("testConfig.ini", "rt");    if(fpcfg == NULL)    {        return -1;    }    while(fgetws(linebuf, sizeof(linebuf), fpcfg) != NULL)    {        //ignore annotation line        if(linebuf[0]=='#' || linebuf[0]==';')        {            continue;        }        //ignore empty line        ptr1 = linebuf;        while(*ptr1==0x20 || *ptr1=='\t')            ptr1++;        if(!*ptr1 || *ptr1=='\n')        {            continue;        }        //search "="        ptr2 = ptr1;        while(*ptr2 && *ptr2!='=')        {            ptr2++;        }        delimiter = *ptr2?ptr2:NULL;        //if current line start with "=", continue next line        if(!delimiter || delimiter==ptr1)        {            continue;        }        //*delimiter = '\0';        ptr2 = delimiter-1;        //ignore blank before "="        while(*ptr2==0x20 || *ptr2=='\t')        {    ptr2--;}        //check key length        k = ptr2-ptr1+1;        if(k>(int)sizeof(var)-1)        {            //The key name is out of length."            continue;        }        //save key name        ptr2 = var;        while(k--)        {            *ptr2++ = *ptr1++;        }        *ptr2 = '\0';        //locate value's start point(may be '\0')        ptr1 = delimiter+1;        //ignore blank after "="        while(*ptr1==0x20 || *ptr1=='\t')        {            ptr1++;        }        //set ptr2 point to line end        ptr2 = linebuf;        while(*ptr2)        {ptr2++;}        ptr2--;        if(*ptr2=='\n')        {            *ptr2-- = '\0';        }        //ignore blank line end        //if value is empty,ptr2 --> = , ptr1>ptr2        while(*ptr2==0x20 || *ptr2=='\t' )        {            ptr2--;        }        //check value length        k = ptr2-ptr1+1;        if(k>(int)sizeof(val)-1)        {            //The value is out of length"            continue;        }        //save value        ptr2 = val;        while(k-->0)        {            *ptr2++ = *ptr1++;        }        *ptr2 = '\0';        if(wcsncmp(var,key, wcslen(var) > wcslen(key) ? wcslen(var) : wcslen(key))==0){            wcsncpy(value,val, wcslen(val));            return 0;        }    }    fclose(fpcfg);    fpcfg = NULL;    return -1;}

恩，再来个main方法测试下：

int _tmain(int argc, wchar_t* argv[]){    wchar_t value[256] = {
    0};    wchar_t keyParam[256] = L"ip";    wchar_t *temp = (wchar_t *)malloc(sizeof(wchar_t) * 256);    if(temp != NULL){        memset(temp, 0x00, sizeof(wchar_t) * 256);    }else{        return -1;    }    if(0 == GetValue(keyParam, temp)){        wcsncpy(value, temp, wcslen(temp));        wprintf(L"Found:  %s\n", value);    }else{        wprintf(L"Not Found!!\n");    }    if(temp != NULL)    {        free(temp);            temp = NULL;    }    return 0;}

 

好吧，这确实是个很丑陋的版本，仅供自己留着备用。
