lock transaction does not work

[Manfred W. <e95...@st...>]

Today I tried the bugfix of the lock transaction (ie. the cvs-version
from the last weekend) and hoped that it worked now. But I am sorry to
tell you that it still does not work. I tried a compare_swap-operaton
using a code like this:

int errorcode=raw1394_lock(rawhandle, 0xffc0 | NodeID,
0xfffff0000904ull,
                           2, new_oPCR0, old_oPCR0, &test_oPCR0);

(where *_PCR0 are of the type quadlet_t).

But this does return errorcode=-1004. Does anybody know, what this
errorcode means? I have no idea. I know that node id and address are ok,
because I successfully do a raw1394_read to the same position
immediately before the lock.

It would be nice, if somebody could help me.
