Re: [rsf-devel] 64-bit platform and large file I/O

Vladimir,

Yes, sftransp will have to be modified to deal with a case like yours.
For now, I have added a check to prevent overflow:
http://rsf.svn.sourceforge.net/viewvc/rsf/trunk/system/main/transp.c?r1=7107&r2=7262

You can try to do "transp plane=13" in two steps "transp plane=12 |
transp plane=23" to reduce memory requirements.
