userpw.h AIX ( delete entry from the shadow password database )
HI i need to delete an entry in /etc/security/passwd.
can't find a way to do it with userpw.h api ( AIX ).
the passwd file i delete like this.
Write all entrys to passwd file except the one we are removing.
can't find any function that works like getspent / getpwent do
in AIX userpw api. How do i delete an entry in the shadow file on AIX?
while ((p = getpwent()) != NULL) {
/* Update passwd file if it's not the user we are removing */
if(!(typ==3 && strcmp(p->pw_name,user) == 0)) {
putpwent(p, fpb);
}
}

Does anyone know how to remove a stanza in the shadow password file if the user account has already been removed on an AIX box? I know it can be done by editing the file itself but I would prefer not to do it that way.
cheers

fgetpwent
FGETPWENT(3) Linux Programmer's Manual FGETPWENT(3)
NAME
fgetpwent - get password file entry
SYNOPSIS
#include <pwd.h>
#include <stdio.h>
#include <sys/types.h>
struct passwd *fgetpwent(FILE *stream);
DESCRIPTION
The fgetpwent() function returns a pointer to a structure containing the broken out fields of a line in the file stream. The first time it
is called it returns the first entry; thereafter, it returns successive entries. The file stream must have the same format as /etc/passwd.
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 fgetpwent() function returns the passwd structure, or NULL if there are no more entries or an error occurs.
ERRORS
ENOMEM Insufficient memory to allocate passwd structure.
FILES
/etc/passwd
password database file
