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.
