编译问题????

netsmile

#include<errno.h>
int main(int argc,char **argv)
{
char *filename;
struct stat statbuf;
filename=argv[1];


if(argc!=2)
{
printf("Euage:%s filename\n",argv[0]);
exit(1);
}
if(stat(filename,statbuf)==-1)
       {
        printf("Get stat on %s Error:%s\n",filename,strerror(errno));
        exit(1);
       }
if(S_ISDIR(statbuf.st_mode))
{
printf("is's directory!");
exit(1);
}
if(S_ISREG(statbuf.st_mode))
{
printf("file size is %d",statbuf.st_off);
printf("file uid is %d",statbuf.st_uid);
}
exit(1);
}

用gcc -o stat1 stat1.c总是说
storage size of'statbuf'is't known

怎么回事,帮忙,我刚学linux编程.

好像你的struct还没定义哦.

加上这几个头文件<unistd.h>,<sys/stat.h>,<sys/types.h>就可以了。
