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);
}
}

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 CONFORMING TO
