PAM_SM_CHAUTHTOK(3)        Library Functions Manual        PAM_SM_CHAUTHTOK(3)

NAME
     pam_sm_chauthtok -- service module implementation for pam_chauthtok

LIBRARY
     Pluggable Authentication Module Library (libpam, -lpam)

SYNOPSIS
     #include <&lt;sys/types.h>&gt;

     int
     pam_sm_chauthtok(pam_handle_t *pamh, int flags, int argc, const char
     **argv);

DESCRIPTION
     The pam_sm_chauthtok function is the service module's implementation of
     the pam_chauthtok(3) API function.

     When the application calls pam_chauthtok(3), the service function is
     called twice, first with the PAM_PRELIM_CHECK flag set and then again
     with the PAM_UPDATE_AUTHTOK flag set.
