Hi,
Thanks foe the information. I have created the file
/etc/nsswitch.conf and tried to run the same application, then perror is
printing success, but the password structure address remains 0. My
program and output is given below
#include <unistd.h>
#include <sys/types.h>
#include <stdio.h>
#include <pwd.h>
int main()
{
uid_t uid = 0;
struct passwd *pw=NULL;
uid=getuid();
pw=getpwuid(uid);
perror("error no is");
printf("uid is ===> %d\n",uid);
printf("pw is ===> %d\n",pw);
}
error is ===>: Success
uid is ===> 0
pw is ===> 0
I have tried with getpwnam("root") also, but result ramins same..
Thanks

hi,
While printing the error it displaying " No such file or directory".
What is the default file for getpwuid?...
The man page says this :
NOTE
The user password database mostly refers to /etc/passwd.
However, with recent systems it also refers to network wide databases
using NIS, LDAP and other local files as configured in
/etc/nsswitch.conf.
FILES
/etc/passwd
local password database file
/etc/nsswitch.conf
System Databases and Name Service Switch configuration file
Thanks
