PW_GETCONF(3) BSD Library Functions Manual PW_GETCONF(3)NAME
pw_getconf, pw_getpwconf -- password encryption configuration access function
LIBRARY
System Utilities Library (libutil, -lutil)
SYNOPSIS
#include <util.h>
void
pw_getconf(char *data, size_t len, const char *key, const char *option);
void
pw_getpwconf(char *data, size_t len, const struct passwd *pwd, const char *option);
DESCRIPTION
The pw_getconf() function reads /etc/passwd.conf and retrieves the value of the option specified by option from the section given by key. If
no suitable entry is found for the key an empty string will be returned in data.
To retrieve default values the key default can be used. In this case, if /etc/passwd.conf does not exist or does not contain a default sec-
tion, the built-in defaults will be returned. They are as follows:
option data
ypcipher old
localcipher old
An empty string is returned for all errors.
pw_getpwconf() returns the value for the option specified for the particular user specified in pwd. If that option is not found, then it
tries to find the option in the primary group of that user, and if that fails, then it returns the default entry.
FILES
/etc/passwd.conf
ERRORS
pw_getconf() and pw_getpwconf() will fail if:
[ENOENT] There is no option named option in the specified key.
[ENOTDIR] There is no key in /etc/passwd.conf named key.

The pw_getconf() function first appeared in NetBSD 1.6.

getpwnam, getpwuid - get password file entry
SYNOPSIS
#include <pwd.h>
#include <sys/types.h>
struct passwd *getpwnam(const char *name);
struct passwd *getpwuid(uid_t uid);
DESCRIPTION
The getpwnam() function returns a pointer to a structure containing the broken out fields of a line from /etc/passwd for the entry that
matches the user name name.
The getpwuid() function returns a pointer to a structure containing the broken out fields of a line from /etc/passwd for the entry that
matches the user uid uid.
The passwd structure is defined in <pwd.h> as follows:
struct passwd {
char *pw_name; /* user name */
char *pw_passwd; /* user password */
uid_t pw_uid; /* user id */
gid_t pw_gid; /* group id */
char *pw_gecos; /* real name */
char *pw_dir; /* home directory */
char *pw_shell; /* shell program */
};
RETURN VALUE
The getpwnam() and getpwuid() functions return a pointer to the passwd structure, or NULL if the matching entry is not found or an error
occurs.
ERRORS
ENOMEM Insufficient memory to allocate passwd structure.
FILES
/etc/passwd

Introduction
I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:
$ ls -ld /usr/bin /usr/bin/cat
drwxrwxr-x 3 root bin 8704 Sep 23 2004 /usr/bin
-r-xr-xr-x 1 bin bin ... (6 Replies)
I have a file which looks roughly like this:
996 mmmmmmm
996 xxxxxxxxxxxxx
99600 ssssssssss
9964 fffffffffffff
and would like to sort it numerically on the first field. I tried:
sort -nr --key=1 ....
The output I get is:

Suppose I have a main() function with only one malloc statement allocating say some 1 gb memory. Also say my system has 1 gb of ram.
main()
{
malloc(1gb)
return(0)
}
The program above exits without freeing the memory.
In this case will the 1 gb of heap memory be returned... (9 Replies)
I'm trying to install a PGX32 video card on my Sparc 10 Ultra running Solaris 10.

Hey All,
Quick question...
I'm writing a short script to check if a continuous port is running on a server.
I'm using "ps -ef | grep -v grep | grep processName" and I was wondering if it was better/more reliable to just check the
return code from the command or if its better to pipe to... (12 Replies)
I installed NetBSD 6.1.2 amd64 and can't find the apm utility. Is it not in the base system?
Is it necessary to recompile the default amd64 kernel to use apm?
Or is there a new method for power management and suspend/resume? (2 Replies)
Hi,
I am learning shell scripting for the first time. I use AT&T Korn Shell, Version AJM 93u+ 2012-08-01, compiled from source on NetBSD.
So far I have managed to set up what I think is a useful and pleasing shell prompt, which can be seen in the image attached to this post.
The prompt is... (2 Replies)
Hey gang, I have a list of times I need to sum up. This list can vary from a few to a few thousand entries.

Usually when I on the evening go to bed I take some interesting book with me. I read it for a while to get me down to sleep. Probably most people seek information from the Nett by googleing but I am so oldfashioned I prefer a real book ;)
But what a book. The one I found and ordered is BSD Unix®... (0 Replies)
