Field Documentation
char* globus_gass_transfer_proto_descriptor_t::url_scheme
URL Scheme. The URL scheme which this protocol module supports. The
scheme is the first part of a URL, which names the protocol which is
used to access the resource named by the URL, for example ’http’ or
’ftp’.
The GASS Transfer library allows only one protocol module to be
registered to handle a particular url_scheme. However, a protocol
module may implement only the client or only the server part of the
protocol. If a protocol has several variations with different scheme
names (for example http and https), each scheme must be registered with
GASS in order to be used.
globus_gass_transfer_proto_new_attr_t
globus_gass_transfer_proto_descriptor_t::new_requestattr
New request attributes. The function pointed to by this pointer is used
by GASS to forward requests to create a request attribute for this
protocol’s url_scheme to the protocol module. The function returns a
request attribute which inherits from one of the GASS Transfer request
attributes.

globus_gass_transfer_proto_new_attr_t
globus_gass_transfer_proto_new_request_t
globus_gass_transfer_proto_descriptor_t::new_request
New request. The function pointed to by this pointer is used by GASS to
initiate a new file transfer request by a protocol module. The request
handle has been initialized with the parameters passed to one of the
functions in the Client-Initiated Operations section of the GASS
Transfer API.
The protocol module should begin processing this request by sending
appropriate messages to the file server. Once the request is
authorized, denied, or referred, the protocol module calls
globus_gass_transfer_proto_request_ready(),
globus_gass_transfer_proto_request_denied(), or
globus_gass_transfer_proto_request_referred().

globus_gass_transfer_proto_new_attr_t
globus_gass_transfer_proto_descriptor_t::new_listenerattr
New listener attributes. The function pointed to by this pointer is
used by GASS to forward requests to create a listener attribute for
this protocol’s url_scheme to the protocol module. The function returns
a listener attribute which inherits from one of the GASS Transfer
request attributes.

globus_gass_transfer_proto_create_listener_t
globus_gass_transfer_proto_descriptor_t::new_listener
New listener. The function pointed to by this pointer is used by GASS
to create a new listener handle. The listener handle has been
initialized with the parameters passed to one of the functions in the
Client-Initiated Operations section of the GASS Transfer API.
The protocol module should begin processing this request by sending
appropriate messages to the file server. Once the request is
authorized, denied, or referred, the protocol module calls
globus_gass_transfer_proto_request_ready(),
globus_gass_transfer_proto_request_denied(), or
globus_gass_transfer_proto_request_referred().
