将writelogs的参数（logname除外）连接起来，写成一条日志,我的程序写错了，帮帮忙看下

我急用，请帮帮忙：）

writelogs('a',0x111,0x1,0x1111,'hello,it is a test1');
用双引号表示字符串，但引号是表示字符

writelogs的参数int errcode,int errrate,int suberrcode也要转换成字符串

[jourmen]

可以详细的帮我改下吗？
谢谢！

[njtu]

int writelogs(char logname[],int errcode,int errrate,int suberrcode,unsigned char *msg)
{
FILE *fp;
char buf[100];
buf[0] = '\0';
//分隔符我没加，自己改
strcat(buf,itoa(errcode));
strcat(buf,itoa(errrate));
strcat(buf,itoa(suberrcode));
strcat(buf,msg);

/******mkfile-start*******/

if((fp=fopen(logname,"a"))==NULL)
{
printf("error");
exit(0);
}
fwrite(buf,sizeof(buf),fp);
fclose(fp);
}


看你想怎么用，也可以使用fprintf(),也许更方便

[jourmen]

还是不可以，调试通不过
大家在给我看看：
# include <stdio.h>
# include <string.h>
int writelogs(char logname[],char errcode,char errrate,char suberrcode,char msg);

int main(void)
{
writelogs("a","0x111","0x1","0x1111","hello,it is a test1");
writelogs("b","0x222","0x1","0x3333","hello,it is a test2");

return 0;
}


int writelogs(char logname[],char errcode,char errrate,char suberrcode,char msg)
{
FILE *fp;
char buf[1000];
buf[0] = '\0';
strcat(buf,errcode);
strcat(buf,errrate);
strcat(buf,suberrcode);
strcat(buf," ");
strcat(buf,msg);

/******mkfile-start*******/

if((fp=fopen(logname,"a"))==NULL)
{
printf("error");
exit(0);
}
fwrite(buf,sizeof(buf),1,fp);
fclose(fp);
return 0;
}

生成的日志记录要是ASCII的，不可以是二进制流的
我急用，日记名是通过logname生成的。
而且日记要每行一条

怎么坐呢，我好久没有用c了，：（

[njtu]

//编译通过，in dev c++

# include <stdio.h>
# include <string.h>
int writelogs(char* logname,char* errcode,char* errrate,char* suberrcode,char* msg);

int main(void)
{
writelogs("a","0x111","0x1","0x1111","hello,it is a test1");
writelogs("b","0x222","0x1","0x3333","hello,it is a test2");

return 0;
}


int writelogs(char* logname,char* errcode,char* errrate,char* suberrcode,char* msg)
{
FILE *fp;
char buf[1000];
buf[0] = '\0';
strcat(buf,errcode);
strcat(buf,errrate);
strcat(buf,suberrcode);
strcat(buf," ");
strcat(buf,msg);

/******mkfile-start*******/

if((fp=fopen(logname,"a"))==NULL)
{
printf("error");
return 0;
}
fwrite(buf,sizeof(buf),1,fp);
fclose(fp);
return 0;
}
