Unlikely. The XDR library uses ANSI stdio (fread/fwrite), which (AFAICT) never return short counts. Even if you make the underlying pipes non-blocking, fread/fwrite are going to block until they have read/written all of the data. -- Glynn Clements <[EMAIL PROTECTED]> _______________________________________________ grass-dev mailing list [email protected] http://grass.itc.it/mailman/listinfo/grass-dev
