Detailed Description

       GSS Assist Header.

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.
