Detailed Description

       GASS Transfer Client Operations.

       Client-Initiated Operations

       One mode of using the GASS Transfer API is to initiate file transfers. The operations supported by the
       GASS Transfer API are file get, put, and append. These operations are provided for HTTP, and HTTPS file
       servers. The protocol module interface allows support for additional protocols to be added easily.

       The GASS transfer library provides both blocking and non-blocking versions of all its client functions.
       When a blocking function completes, or the non-blocking function's callback is called, the user should
       check the request's status to discover whether the transfer was completed successfully, denied, or
       referred.

Function Documentation

   int globus_gass_transfer_append (globus_gass_transfer_request_t * request, globus_gass_transfer_requestattr_t
       * attr, char * url, globus_size_t length)
       Blocking file append.

       This function initiates a new 'append' request of the file named by url. The entire file will be
       transferred to the server if the user is authorized to do so. This function blocks until the GASS library
       has determined whether the file may be retrieved by the caller, may not because it is a referral to
       another URL or URLs, or the server has denied the request.

       Upon returning from this function, the request handle is initialized to refer to the append request's
       state.

       If the server can't store the file at url, but has an alternative location for the user to store to, then
       this function return with request's status set to GLOBUS_GASS_TRANSFER_REQUEST_REFERRED.

       Parameters
           request A pointer to an uninitialized request handle.
           attr Request attributes.
           url URL to append to.
           length The length of the data to append to the url, if known. If this parameter is set to
           GLOBUS_GASS_LENGTH_UNKNOWN, then the append may fail if the protocol does not support arbitrarily-
           length files.

       Return values
           GLOBUS_SUCCESS The put was successfully initiated.
           GLOBUS_GASS_TRANSFER_ERROR_NULL_POINTER One of request, attr, or callback was GLOBUS_NULL. The put
           could not be processed.
           GLOBUS_GASS_TRANSFER_ERROR_INTERNAL_ERROR An internal resource was not available to process the put.
           GLOBUS_GASS_TRANSFER_ERROR_NOT_IMPLEMENTED No protocol handler for doing a append on this URL type is
           implemented.
           GLOBUS_GASS_TRANSFER_ERROR_BAD_URL The URL could not be parsed.

   int globus_gass_transfer_get (globus_gass_transfer_request_t * request, globus_gass_transfer_requestattr_t *
       attr, char * url)
       Blocking file get.

       This function initiates a new 'get' request of the file named by url. The entire file will be transferred
       from the server if the file exists and user is authorized to do so. This function blocks until the GASS
       library has determined whether the file may be retrievied by the caller, may not because it is a referral
       to another URL or URLs, or the server has denied the request.

       Upon returning from this function, the request handle is initialized to refer to the get request's state.
       This request handle must be destroyed after the user has finished processing the data associated with the
       callback.

       If the file doesn't exist at url, but a referral does, then this function will return with the request's
       status set to GLOBUS_GASS_TRANSFER_REQUEST_REFERRED.

       Parameters
           request A pointer to an uninitialized request handle.
           attr Request attributes.
           url URL to get

       Return values
           GLOBUS_SUCCESS The get was successfully initiated.
           GLOBUS_GASS_TRANSFER_ERROR_NULL_POINTER One of request or attr was GLOBUS_NULL. The get could not be
           processed.
           GLOBUS_GASS_TRANSFER_ERROR_INTERNAL_ERROR An internal resource was not available to process the get.
           GLOBUS_GASS_TRANSFER_ERROR_NOT_IMPLEMENTED No protocol handler for doing a get on this URL type is
           implemented.
           GLOBUS_GASS_TRANSFER_ERROR_BAD_URL The URL could not be parsed.

   int globus_gass_transfer_put (globus_gass_transfer_request_t * request, globus_gass_transfer_requestattr_t *
       attr, char * url, globus_size_t length)
       Blocking file put.

       This function initiates a new 'put' request of the file named by url. The entire file will be transferred
       to the server if the user is authorized to do so. This function blocks until the GASS library has
       determined whether the file may be retrieved by the caller, may not because it is a referral to another
       URL or URLs, or the server has denied the request.

       Upon returning from this function, the request handle is initialized to refer to the put request's state.

       If the server can't store the file at url, but has an alternative location for the user to store to, then
       this function return with request's status set to GLOBUS_GASS_TRANSFER_REQUEST_REFERRED.

       Parameters
           request A pointer to an uninitialized request handle.
           attr Request attributes.
           url URL to put.
           length The length of the data to put to the url, if known. If this parameter is set to
           GLOBUS_GASS_LENGTH_UNKNOWN, then the put may fail if the protocol does not support arbitrarily-length
           files.

       globus_gass_transfer_callback_t callback, void * user_arg)
       Nonblocking file append.

       This function initiates a new 'append' request of the file named by url. The entire file will be
       transferred to the server if the user is authorized to do so. This function does not block; instead, the
       user's callback function will be called once the GASS library has determined whether the file may be
       stored or not.

       Upon returning from this function, the request handle is initialized to refer to the append request's
       state.

       If the server can't store the file at url, but has an alternative location for the user to store to, then
       the callback function will be called with the request's status set to
       GLOBUS_GASS_TRANSFER_REQUEST_REFERRED.
