NAME

     pam_sm_chauthtok -- service module implementation for pam_chauthtok


SYNOPSIS

     #include <sys/types.h>
     #include <security/pam_appl.h>
     #include <security/pam_modules.h>

     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

     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.
