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 the realm the principal belongs to.

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

       const Shisa_principal * ph
                   Pointer to an existing principal structure containing information to store  in
                   the database.

DESCRIPTION

       Modifies  information  stored  about the given principal PRINCIPAL@REALM.  Note that it is
       usually a good idea to set in ph only the fields that are to be updated.

       It is generally suggested  to  first  call  shisa_principal_find(),  to  get  the  current
       information, then to modify one field and call shisa_principal_update().

       Modifying  several  values  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 otherwise.
