NAME

       shisa_principal_update - API function

SYNOPSIS

       #include <shisa.h>

       int  shisa_principal_update(Shisa * dbh, const char * realm, const char * principal, const
       Shisa_principal * ph);

ARGUMENTS

       Shisa * dbh Shisa library handle created by shisa().

       const char * realm
                   Name of realm the principal belongs in.

       const char * principal
                   Name of principal to get information on.

       const Shisa_principal * ph
                   Pointer to principal structure with information to store in database.

DESCRIPTION

       Modify information stored for given PRINCIPALREALM.  Note that it is usually a  good  idea
       to  only  set  the  fields  in  ph  that you actually want to update.  Specifically, first
       calling shisa_principal_find() to get the current information, then modifying  one  field,
       and  calling  shisa_principal_update()  is  not  recommended  in  general, as this will 1)
       overwrite any modifications  made  to  other  fields  between  the  two  calls  (by  other
       processes)  and  2)  will  cause  all  values to be written again, which may generate more
       overhead.

RETURN VALUE

       Returns SHISA_OK if successful, SHISA_NO_REALM if the  indicated  realm  does  not  exist,
       SHISA_NO_PRINCIPAL if the indicated principal does not exist, or an error code.
