NAME
     getuserattr,    getusernam,    getuseruid,    free_userattr,
     setuserattr, enduserattr, fgetuserattr - get user_attr entry

SYNOPSIS
     cc [ flag... ] file... -lsecdb  -lsocket  -lnsl [ library... ]
     #include 

     userattr_t *getuserattr(void);


     userattr_t *getusernam(const char *name);


     userattr_t *getuseruid(uid_t uid);


     void free_userattr(userattr_t *userattr);


     void setuserattr(void);


     void enduserattr(void);


     userattr_t *fgetuserattr(FILE *f);


DESCRIPTION
     The getuserattr(), getusernam(), and getuseruid()  functions
     each  return a user_attr(4) entry. Entries can come from any
     of the sources specified in the nsswitch.conf(4)  file.  The
     getuserattr()  function  enumerates  user_attr  entries. The
     getusernam() function searches for a user_attr entry with  a
     given user name name. The getuseruid() function searches for
     a user_attr entry with a given user ID uid. Successive calls
     to   these  functions  return  either  successive  user_attr
     entries or NULL.


     The fgetuserattr() function does not use  nsswitch.conf  but
     reads  and  parses  the  next  line  from the stream f. This
     stream is assumed to have the format of the user_attr files.


     The free_userattr() function releases  memory  allocated  by
     the  getusernam(),  getuserattr(),  and fgetuserattr() func-
     tions.

     The internal  representation  of  a  user_attr  entry  is  a
     userattr_t  structure defined in  with the fol-
     lowing members:

       char  *name;       /* name of the user */
       char  *qualifier;  /* reserved for future use */
       char  *res1;       /* reserved for future use */
       char  *res2;       /* reserved for future use */
       kva_t *attr;       /* list of attributes */



     The setuserattr() function "rewinds" to the beginning of the
     enumeration of user_attr entries.  Calls to getusernam() may
     leave  the  enumeration  in  an  indeterminate   state,   so
     setuserattr()  should  be  called  before  the first call to
     getuserattr().


     The enduserattr() function may be called  to  indicate  that
     user_attr processing is complete; the library may then close
     any open user_attr file, deallocate  any  internal  storage,
     and so forth.

RETURN VALUES
     The getuserattr() function returns a pointer to a userattr_t
     if it successfully enumerates an entry; otherwise it returns
     NULL, indicating the end of the enumeration.


     The getusernam() function returns a pointer to a  userattr_t
     if it successfully locates the requested entry; otherwise it
     returns NULL.

USAGE
     The getuserattr() and getusernam() functions  both  allocate
     memory  for  the pointers they return. This memory should be
     deallocated with the free_userattr() function.


     Individual attributes can be referenced in the  attr  struc-
     ture by calling the kva_match(3SECDB) function.

WARININGS
     Because the list of legal keys is  likely  to  expand,  code
     must  be  written  to ignore unknown key-value pairs without
     error.

FILES
     /etc/user_attr        extended user attributes
