source: trunk/packages/vizservers/nanovis/nanovisServer.h @ 4105

Last change on this file since 4105 was 4105, checked in by ldelgass, 9 years ago

Prep servers for accepting arguments to change file descriptors for IO. This
will allow us to send stdout to the trace log along with stderr so chatty
libraries won't send garbage to the socket. Fall back to stdin/stdout to allow
debugging without nanoscale.
