Writing a User Entry
--------------------

 - Function: int putpwent (const struct passwd *P, FILE *STREAM)
     This function writes the user entry `*P' to the stream STREAM, in
     the format used for the standard user database file.  The return
     value is zero on success and nonzero on failure.

     This function exists for compatibility with SVID.  We recommend
     that you avoid using it, because it makes sense only on the
     assumption that the `struct passwd' structure has no members
     except the standard ones; on a system which merges the traditional
     Unix data base with other extended information about users, adding
     an entry using this function would inevitably leave out much of
     the important information.

     The function `putpwent' is declared in `pwd.h'.
