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

NAME
getpw - Re-construct password line entry
SYNOPSIS
#include <pwd.h>
#include <sys/types.h>
int getpw(uid_t uid, char *buf);
DESCRIPTION
The getpw() function re-constructs the password line entry for the given user uid uid in the buffer buf. The returned buffer contains a
line of format
name:passwd:uid:gid:gecos:dir:shell
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 getpw() function returns 0 on success, or -1 if an error occurs.
ERRORS
ENOMEM Insufficient memory to allocate passwd structure.
FILES
/etc/passwd
password database file
CONFORMING TO
SYSVr2.
BUGS
The getpw() function is dangerous as it may overflow the provided buffer buf. It is obsoleted by getpwuid().
