+Example 9 : Show the method of using lstatcall and struct stat to display file attributes
+
+ ****************************************************************
+
+ Answer :
+
+ INSTRUCTIONS :
+
+ 1.These programs are part of systems programming in Unix and the commands have NO EQUIVALENT IN SCILAB
+
+ 2.However if possible some selected programmes have been TRIED TO BE IMPLEMENTED
+
+ 3.For most of the programmes whose equivalent is NOT THERE IN SCILAB,only the output has been printed as given in the textbook w
+ ith no interactive input as in the programme below
+
+ 4.However the .c files which are displayed here are also made into a seperate file.If you are a unix user then try compiling and
+ running the programme with gcc or cc compiler
+
+ 5.The inconvenience is regretted.
+.............Press [ENTER] to continue..... UNIX SHELL SIMULATOR(DEMO VERSION WITH PRELOADED COMMANDS)
+
+
+
+
+$ cat attributes.c # to open the file emp.lst /* Program: attributes.c -- Uses lstat call and struct stat to display file attributes */
+#include <stdio.h>
+#include <sys/stath>
+
+void quit(char *,int);
+
+int main(int argc, char**argv) {
+ struct stat statbuf; /*We'll use lstat to populate this*/
+
+ if (lstat(argv[1], &statbuf) == -1)
+ quit("Couldn't stat file", 1);
+
+ printf("File: %s\n",argv[1]);
+ printf("Inode number: %d \n",statbuf.st_ino);
+ printf("UID: %d ",statbuf.st_uid);
+ printf("GID: %d \n",statbuf.st_gid);
+ printf("Types and Permissions: %o\n",statbuf.st_mode);
+ printf("Number of links: %d \n",statbuf.st_nlink);
+ printf("Size in bytes: %d\n",statbuf.st_size);
+ printf("Blocks allocated: %d\n",statbuf.st_blocks);
+ printf("Last Modification Time: %s\n",ctime(&statbuf.st_mtime));
+ printf("Last Access Time: %s\n",ctime(&statbuf.st_atime));
+ exit(0);
+}
+ $ cc dir.c
+
+
+Here it displays a mock value since it is windows
+
+
+$ a.out /etc/passwd
+File: /etc/passwd
+Inode number: 54412
+UID: 0 GID: 3
+Type and Permissions: 100755
+Number of links: 1
+Size in bytes: 10803
+Blocks allocated: 22
+Last Modification Time: Tue Nov 19 16:29:13 2002
+Last Access Time: Tue NOv 26 19:57:01 2002
+
+
+
+$ exit #To exit the current simulation terminal and return to Scilab console
+
+........# (hit [ENTER] for result)
+
+ BACK TO SCILAB CONSOLE...
