putpwent(3c)

Standard C Library Functions                                      putpwent(3C)



NAME
       putpwent - write password file entry

SYNOPSIS
       #include <pwd.h>

       int putpwent(const struct passwd *p, FILE *f);

DESCRIPTION
       The putpwent() function is the inverse of getpwent(). See getpwnam(3C).
       Given a pointer to a passwd  structure  created  by  getpwent(),  getp‐
       wuid(),  or  getpwnam(),  putpwent() writes a line on the stream f that
       matches the format of /etc/passwd.

RETURN VALUES
       The putpwent() function returns  a  non-zero  value  if  an  error  was
       detected during its operation. Otherwise, it returns 0.

USAGE
       The  putpwent()  function  is  of  limited utility, since most password
       files are maintained as Network Information Service  (NIS)  files  that
       cannot  be updated with this function. For this reason, the use of this
       function is discouraged. If used at all, it should be  used  with  put‐
       spent(3C) to update the shadow file.
