.SH SYNOPSIS
|
|
|
|
.nf
|
|
|
|
#include <curl/curl.h>
|
|
|

.SH DESCRIPTION
|
|
|
|
Pass a pointer to a \fIcurl_off_t\fP to receive the identifier of the
|
|
|
|
current/last transfer done with the handle. Stores \-1 if no transfer
|
|
|
|
has been started yet for the handle.
|
|
|
|
|
|
|
|
The transfer id is unique among all transfers performed using the same
|
|
|
|
connection cache. This is implicitly the case for all transfers in the
|
|
|
|
same multi handle.
