任何人都可以找出这段代码中的问题。问题是它为所有路径名显示相同的输出，即使它们具有不同的内容、不同的文件。
#include<stdio.h>
#include<sys/stat.h>
#include<unistd.h>
#include<sys/types.h>
#include<sys/vfs.h>
int main(int argc,char *argv[])
{
struct statfs sb;
if((statfs(argv[1],&sb))==0)
{
printf("optimal transfer blk size is %d\n",sb.f_bsize);
printf("total data blocks are %d\n",sb.f_blocks);
printf("free blocks in fs are %d\n",sb.f_bfree);
printf("total file nodes in fs are %d\n",sb.f_files);
printf("free file nodes in fs are %d\n",sb.f_ffree);
}
}
[testuser@hdchshocms6344 ex4]$ ./a.out /home/testuser
optimal transfer blk size is 4096
total data blocks are 8819390
free blocks in fs are 6771045
total file nodes in fs are 2240224
free file nodes in fs are 1927385
