NAME

       shisa_key_update - API function

SYNOPSIS

       #include <shisa.h>

       int  shisa_key_update(Shisa  *  dbh,  const  char  *  realm, const char * principal, const
       Shisa_key * oldkey, const Shisa_key * newkey);

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 remove key for.

       const Shisa_key * oldkey
                   Pointer to Shisa key structure with hints on matching the key to modify.

       const Shisa_key * newkey
                   Pointer to Shisa key structure with new values for  the  key,  note  that  all
                   fields are used (and not just the ones specified by oldkey).

DESCRIPTION

       Modify  data  about a key in the database, for the given PRINCIPALREALM.  First the oldkey
       is used to locate the key to update (similar  to  shisa_keys_find()),  then  that  key  is
       modified  to contain whatever information is stored in newkey.  Not all elements of oldkey
       need to be filled out, only enough as to identify the key uniquely.  For example,  if  you
       want  to  modify the information stored for the only key with an etype of 3 (DES-CBC-MD5),
       set the key->etype field to 3, and set all other fields to 0.

RETURN VALUE

       Returns  SHISA_OK  on  success,  SHISA_NO_KEY  if  no  key  could   be   identified,   and
       SHISA_MULTIPLE_KEY_MATCH  if  more  than  one  key matched the given criteria, or an error
       code.
