NAME
       sia_chg_finger, sia_chg_password, sia_chg_shell - SIA change routines (Security Integration Architecture)

LIBRARY
       Standard C library (libc.so and libc.a)

SYNOPSIS
       #include <sia.h>
       #include <siad.h>

       int sia_chg_finger(
	    int (*collect)(),
	    char *username,
	    int argc,
	    char *argv[]);

       int sia_chg_password(
	    int (*collect)(),
	    char *username,
	    int argc,
	    char *argv[]);

       int sia_chg_shell(
	    int (*collect)(),
	    char *username,
	    int argc,
	    char *argv[]);

PARAMETERS
       collect	   The collect parameter is a pointer to an SIA collection routine.  If this pointer is NULL, no collection is possible.  The col-
		   lect parameter should never be NULL.  This parameter is read only.

		   Further information on the SIA change routines is available from the interface specifications in /usr/include/{sia,siad}.h.

       username    The username parameter is used when a precollected username is available.  The username parameter either points to the  precol-
		   lected username or is set to NULL if no username exists.  This parameter is read only.

       argc	   The argc parameter is the number of arguments used when invoking the calling command or utility.  This parameter are read only.

       argv	   The	argv  parameter  is  the  array of arguments used when invoking the calling command or utility.  The argv[0] variable must
		   always be set to the calling commands name.	This is used for logging or auditing of the password change function.

DESCRIPTION
   sia_chg_finger()
       The sia_chg_finger() routine is used to change information about users in the /etc/passwd file.	This information is  used  by  the  finger
       program,  among	others.  The user is offered a menu to choose which security mechanism is  relevant to this invocation. If only one choice
       is available that security mechanism is called directly.

   sia_chg_password()
       The sia_chg_password() routine is used to change the password in the security mechanism's database; for base security, its /etc/passwd  and
       for enhanced security its auth.db.  If NIS is running, the password change is made in /var/yp/src/passwd or /var/yp/src/prpasswd files.

       The routine assumes that the user might be registered with multiple security mechanisms and that those security mechanisms do not support a
       common distributed transaction update capability. Consequently the sia_chg_password() routine  first  calls  the  siad_chk_user()  security
       dependent  routine  to  obtain  a  list of relevant security mechanisms to offer to the calling user.  The user is offered a menu to choose
       which security mechanism is  relevant to this invocation of password change. If only one choice is available  that  security  mechanism	is
       called directly.

   sia_chg_shell()
       The  sia_chg_shell()  routine  is used to change the login shell field of the /etc/passwd file.	The user is offered a menu to choose which
       security mechanism is  relevant. If only one choice is available that security mechanism is called directly.

RETURN VALUES
       The sia_chg_*() routines return SIASUCCESS when the are successful and SIAFAIL when they are not successful.

ERRORS
       The errno value is not (normally) set explicitly by sia_* routines.  The errno values are those returned from the dynamic loader interface,
       from  dependent	(siad_*)  routines,  or  from malloc.  Possible errors include resource constraints (no memory) and various authentication
       failures.

FILES
       /etc/passwd

       /etc/sia/matrix.conf
