#15837: xfer: regression in API 3.x.x compared to 2.10.x
---------------------+-----------------------
Reporter: stefanb | Owner:
Type: defect | Status: new
Milestone: 3.0.0 | Component: libpurple
Version: | Keywords: API 3.x.x
---------------------+-----------------------
The API for the xfer read callback has not changed since API 2.10.x
{{{
void purple_xfer_set_read_fnc(PurpleXfer *xfer,
gssize (*fnc)(guchar **,
PurpleXfer *)
);
}}}
What **has** changed is that `xfer->current_buffer_size` is no longer
available. This value is required by the read callback to determine how
many bytes can fit into the provided buffer.
Proposed fixes:
* add a new `purple_xfer_get_current_buffer_size(xfer)` API function
* change the function prototype for `fnc` to include the buffer size.
Noticed when I tried to update third-party SIPE plugin to the latest API
3.x.x version (changeset: 35114:b833eaa6c76f)
