.PP
Send a GridFTP ABORT\&. This function is used to send the ABORT message to the FTP server\&. The ABORT message is sent out-of-band, and terminates any current data transfer in progress\&.
.PP
As a result of the ABORT, the data channels used by this control channel will be closed\&. The data command callback will be issued with either a completion reply, or a transfer aborted reply\&. The ABORT callback will also be invoked, with the server's response to the abort command\&.
.PP
Any attempts to register buffers for read or write after an ABORT has been sent will fail with a 'no transfer in progress' error\&.
.PP
\fBParameters\fP
.RS 4
\fIhandle\fP A pointer to a GridFTP control handle\&. The ABORT command is issued to the server over the control channel associated with this handle\&.
