我有以下课程
class Cdata12Mnt
{
public:
char IOBname[ID1_IOB_PIOTSUP-ID1_IOB_TOP][BOADNAM_MAX + 4];
char ExIOBname[ID1_MAX_INF-ID1_EXIOB_U1TOP][BOADNAM_MAX + 4];
char cflpath[256];
char basetext[256];
UINT database[ID1_MAX_INF];
int State;
public:
char SelectPath[256];
public:
int GetIOBName(int slt,char *Name);
Cdata12Mnt(char *SelectPath);
virtual ~Cdata12Mnt();
int GetValue(int id);
int GetState() { return State; }
};
我的功能如下
Cdata12Mnt::Cdata12Mnt(char *SelectPath)
{
SCTReg reg;
char buf[256], *cpnt, *npnt, *bpnt1, *bpnt2;
char *startcode[] = {"CNTL_CODE ","SEGMENT "};
char *stopcode = {"END_CNTL_CODE "};
FILE *fp;
int ii, infl;
State = 0;
for (ii = 0; ii < (ID1_IOB_PIOTSUP - ID1_IOB_TOP); ii++) {
strcpy(IOBname[ii], "");
}
for (ii = 0; ii < (ID1_MAX_INF-ID1_EXIOB_U1TOP); ii++) {
**strcpy(ExIOBname[ii], "");**
}
sprintf(cflpath, "%s\\%s", SelectPath, CDATAFL);
if ((fp = fopen(cflpath,"r"))!=NULL) {
for (ii = 0, infl = 0; fgets(buf, 256, fp) != NULL;) {
if (infl == 0 && strncmp(buf, startcode[0], strlen(startcode[0])) == 0) {
if ((cpnt = strchr(&buf[strlen(startcode[0])],*startcode[1])) != NULL) {
if (strncmp(cpnt,startcode[1], strlen(startcode[1])) == 0) {
infl = 1;
continue;
}
}
}
if (infl == 0) {
continue;
}
if (strncmp(buf,stopcode,strlen(stopcode))==0) {
if (ii == ID1_EXIOB_U1TOP) {
for (int nDataNumber = ii; nDataNumber < ID1_MAX_INF; nDataNumber++) {
database[nDataNumber] = 0;
}
}
infl = 0;
continue;
}
if (strncmp(&buf[14], " DD ", 4) == 0) {
if ((cpnt=strchr(buf, ';')) != NULL) {
*cpnt = '\0';
}
if (ii >= ID1_IOB_TOP && ii < ID1_IOB_PIOTSUP) {
if ((bpnt1 = strchr(cpnt + 1,'(')) != NULL && (bpnt2=strchr(cpnt + 1,')'))!=NULL && bpnt1 < bpnt2) {
*bpnt2 = '\0';
*(bpnt1 + BOADNAM_MAX + 1) = '\0';
strcpy(IOBname[ii-ID1_IOB_TOP], bpnt1 + 1);
}
}
if (ii >= ID1_EXIOB_U1TOP && ii < ID1_MAX_INF) {
if ((bpnt1 = strchr(cpnt + 1, '(')) != NULL && (bpnt2=strchr(cpnt+1,')'))!=NULL && bpnt1 < bpnt2) {
*bpnt2='\0';
*(bpnt1+BOADNAM_MAX+1)='\0';
strcpy(ExIOBname[ii-ID1_EXIOB_U1TOP], bpnt1 + 1);
}
}
for (cpnt = &buf[18]; cpnt != NULL;) {
if ((npnt=strchr(cpnt, ',')) != NULL)
*npnt='\0';
}
if (strchr(cpnt,'H')!=NULL) {
sscanf(cpnt,"%XH",&database[ii]);
} else {
database[ii]=atoi(cpnt);
}
ii++;
cpnt = npnt;
if (cpnt != NULL) {
cpnt++;
}
}
}
}
fclose(fp);
} else {
State=-1;
}
当我在Visual Studio 2008中编译此函数时,它会在strcpy(IOBname[ii],"");
处给出错误,如下所示
错误C2220:警告被视为错误 - 没有&#39;对象&#39;文件生成
如何解决此错误?
答案 0 :(得分:24)
错误表示警告被视为错误。因此,您的问题是一条警告信息!检查它们并修复它们。
如果您不知道如何找到它们:打开Error List
(View
&gt; Error List
)并点击Warning
。
答案 1 :(得分:8)
转到project properties -> configurations properties -> C/C++ -> treats warning as error -> No (/WX-)
。
答案 2 :(得分:6)
此错误消息非常混乱。我刚刚在我的项目中修复了其他“警告”,我真的只有一个(简单的):
警告C4101:'i':未引用的局部变量
在我评论了这个未使用的i
并编译后,另一个错误就消失了。
答案 3 :(得分:4)
作为旁注,您可以使用#pragma
启用/禁用个别警告。您可以查看文档here
来自文档:
// pragma_warning.cpp
// compile with: /W1
#pragma warning(disable:4700)
void Test() {
int x;
int y = x; // no C4700 here
#pragma warning(default:4700) // C4700 enabled after Test ends
}
int main() {
int x;
int y = x; // C4700
}
答案 4 :(得分:1)
此警告是关于strcpy的不安全使用。请改为IOBname[ii]='\0';
。
