globus_result_t globus_ftp_client_restart_marker_copy (globus_ftp_client_restart_marker_t * new_marker, globus_ftp_client_restart_marker_t * marker)¶

Create a copy of a restart marker.

This function copies the contents of marker to new_marker.

Parameters

See also

globus_result_t globus_ftp_client_restart_marker_destroy (globus_ftp_client_restart_marker_t * marker)¶

Destroy a restart marker.

Parameters

See also

globus_result_t globus_ftp_client_restart_marker_from_string (globus_ftp_client_restart_marker_t * marker, const char * marker_string)¶

Initialize a restart marker from a string.

This function initializes a new restart, marker, based on the marker_string parameter. The string may be either a single offset for a stream-mode restart marker, or a comma-separated list of start-end ranges.

Parameters

See also

globus_result_t globus_ftp_client_restart_marker_get_total (globus_ftp_client_restart_marker_t * marker, globus_off_t * total_bytes)¶

Get total bytes accounted for in restart marker

This function will return the sum of all bytes accounted for in a restart marker. If this restart marker contains a stream offset then this value is the same as the offset (not the ascii offset) that it was set with. If it is a range list, it a sum of all the bytes in the ranges.

Parameters

Returns

globus_result_t globus_ftp_client_restart_marker_init (globus_ftp_client_restart_marker_t * marker)¶

Initialize a restart marker.

Parameters

See also

globus_result_t globus_ftp_client_restart_marker_insert_range (globus_ftp_client_restart_marker_t * marker, globus_off_t offset, globus_off_t end_offset)¶

Insert a range into a restart marker

This function updates a restart marker with a new byte range, suitable for using to restart an extended block mode transfer. Adjacent ranges within the marker will be combined into a single entry in the marker.

The marker must first be initialized by calling globus_ftp_client_restart_marker_init() or globus_ftp_client_restart_marker_copy().

A marker can only hold a range list or a stream offset. Calling this function after calling globus_ftp_client_restart_marker_set_offset() will result in a marker suitable only for use restarting an extended block mode transfer.

Parameters

See also

globus_result_t globus_ftp_client_restart_marker_set_ascii_offset (globus_ftp_client_restart_marker_t * marker, globus_off_t offset, globus_off_t ascii_offset)¶

Set the offset for a restart marker.

This function modifies a restart marker to contain a stream offset, suitable for using to restart a steam mode transfer.

The marker must first be initialized by calling globus_ftp_client_restart_marker_init() or globus_ftp_client_restart_marker_copy().

A marker can only hold a range list or a stream offset. Calling this function after calling globus_ftp_client_restart_marker_insert_range() will delete the ranges associated with the marker, and replace it with a marker suitable only for use restarting a stream mode transfer.

When restarting an ASCII type transfer, use globus_ftp_client_restart_marker_set_ascii_offset() to set both the offset used in the local representation of an ACSII file, and the network representation of the ASCII file. For UNIX systems, the former includes counts newlines as one character towards the file offset, and the latter counts them as 2 characters (CRLF).

Parameters

See also

globus_result_t globus_ftp_client_restart_marker_set_offset (globus_ftp_client_restart_marker_t * marker, globus_off_t offset)¶

Set the offset for a restart marker.

This function modifies a restart marker to contain a stream offset, suitable for using to restart a steam mode transfer.

The marker must first be initialized by calling globus_ftp_client_restart_marker_init() or globus_ftp_client_restart_marker_copy().

A marker can only hold a range list or a stream offset. Calling this function after calling globus_ftp_client_restart_marker_insert_range() will delete the ranges associated with the marker, and replace it with a marker suitable only for use restarting a stream mode transfer.

When restarting an ASCII type transfer, the offset must take into account the additional carriage return characters added to the data stream.

Parameters

See also

globus_result_t globus_ftp_client_restart_marker_to_string (globus_ftp_client_restart_marker_t * marker, char ** marker_string)¶

Create a string representation of a restart marker.

This function sets the marker_string parameter to point to a freshly allocated string suitable for sending as an argument to the FTP REST command, or for a later call to globus_ftp_client_restart_marker_from_string().

The string pointed to by marker_string must be freed by the caller.
