Combine two codes (code 1) to get names with(code 2) to get info:

Code 1:

#include<unistd.h>

#include<sys/types.h>

#include<sys/stat.h>

#include<fcntl.h>

#include<dirent.h>

#include<stdio.h>

#include<stdlib.h>

void do_ls(char []);

int main(int argc,char *argv[])

{

if(argc == 1)

do_ls(".");

else

while(--argc){

printf("%s:\n",*++argv);

do_ls(*argv);

}

}

void do_ls(char dirname[])

{

DIR *dir_ptr;

struct dirent *direntp;

if((dir_ptr = opendir(dirname)) == NULL)

fprintf(stderr,"ls1:cannot open %s\n",dirname);

else

{

while((direntp = readdir(dir_ptr)) != NULL)

printf("%s\n",direntp->d_name);

closedir(dir_ptr);

}

}

code 2:

#include <stdio.h>

#include <sys/types.h>

#include <sys/stat.h>

void show_stat_info(char *, struct stat *);

int main(int argc, char *argv[])

{

struct stat info;

else

perror(argv[1]);

Answer #1

Please find the single c program by concatenating code 1 and 2.

Program:

#include<unistd.h>
#include<sys/types.h>
#include<sys/stat.h>
#include<fcntl.h>
#include<dirent.h>
#include<stdio.h>
#include<stdlib.h>
#include<string.h>


void do_ls(char []);
void show_stat_info(char *fname, struct stat *buf);

int main(int argc,char *argv[])
{
   if(argc == 1)
   {
      do_ls(".");
   }
   else
      while(--argc){
         printf("%s:\n",*++argv);
         do_ls(*argv);
      }
}

void do_ls(char dirname[])
{
   DIR *dir_ptr;
   struct dirent *direntp;
   struct stat info;
   char filePath[1024]= {'\0'};
   size_t remaining = 1024, n = 0;

   if((dir_ptr = opendir(dirname)) == NULL)
   {
      fprintf(stderr,"ls1:cannot open %s\n",dirname);
   }
   else
   {
      while((direntp = readdir(dir_ptr)) != NULL)
      {
         /* Frame the complete path for directory to make stat works */
         strncat(filePath, dirname, remaining);
         strncat(filePath, "/", remaining);
         strncat(filePath, direntp->d_name, remaining);

         if( stat(filePath, &info) != -1 ){

            show_stat_info( filePath, &info );
         }
         memset(filePath, '\0', sizeof(filePath));
      }

      closedir(dir_ptr);
   }
}

void show_stat_info(char *fname, struct stat *buf)
{
   printf(" mode: %o\n", buf->st_mode);
   printf(" links: %d\n", buf->st_nlink);
   printf(" user: %d\n", buf->st_uid);
   printf(" group: %d\n", buf->st_gid);
   printf(" size: %d\n", (int)buf->st_size);
   printf(" modtime: %d\n", (int)buf->st_mtime);
   printf(" name: %s\n", fname );
}

Output:

USER>./a.out ../SHELL/
../SHELL/:

Similarly, modify the Server (conServThread.c) program to accept an argument which is the port number of the server to bind and listen to.
