/* We allow a number of bytes being requested at any given time without

In the sftp_read(), the actually request count is bigger than
buffer_size,so, the previous call will get more data than you want.
I think libssh2_sftp_seek64() must discard the unnecessary request packet
and the data already stored.
LIBSSH2_API void
libssh2_sftp_seek64(LIBSSH2_SFTP_HANDLE *handle, libssh2_uint64_t offset)
{
if(handle) {
handle->u.file.offset = handle->u.file.offset_sent = offset;
sftp_packetlist_flush(handle);
if (handle->u.file.data_left) {
LIBSSH2_FREE(handle->sftp->channel->session, handle->u.file.data);
handle->u.file.data_left = handle->u.file.data_len = 0;
handle->u.file.data = NULL;
}
}
}
