Function Documentation

   globus_result_t globus_gss_assist_authorization_host_name (char * hostname, gss_name_t *
       authorization_hostname)
       Create a GSS Name structure from the given hostname. This function tries to resolve the
       given host name string to the canonical DNS name for the host.

       Parameters:
           hostname The host name or numerical address to be resolved and transform into a GSS
           Name
           authorization_hostname The resulting GSS Name

       Returns:
           GLOBUS_SUCCESS on successful completion, a error object otherwise

   OM_uint32 globus_gss_assist_wrap_send (OM_uint32 * minor_status, const gss_ctx_id_t
       context_handle, char * data, size_t length, int * token_status, int(*)(void *, void *,
       size_t) gss_assist_send_token, void * gss_assist_send_context, FILE * fperr)
       Wrap.

       Parameters:
           minor_status GSSAPI return code. If the call was successful, the minor status is equal
           to GLOBUS_SUCCESS. Otherwise, it is an error object ID for which globus_error_get()
           and globus_object_free() can be used to get and destroy it.
           context_handle the context.
           data pointer to application data to wrap and send
           length length of the data array
           token_status assist routine get/send token status
           gss_assist_send_token a send_token routine
           gss_assist_send_context first arg for the send_token
           fperr file handle to write error message to.

       Returns:
           GSS_S_COMPLETE on success Other GSSAPI errors on failure.
