libvas.a: MiniVas Programming Library
The MiniVas library is a set of subroutines based on the vastools software
provided by Lyon-Lamb. This library is not included.
Using the MiniVas software consists of three basic steps:
At the end of the recording, you may call close_port() to close down
serial communications. The same effect will happen simply by ending the
execution of your program, so this is optional.
Call initmvas(portname) to initialize the serial communications with the MiniVas. portname is the character string of the seri
connected to, (/dev/ttyd1 at ER&E).
Call progmvas(start,framesper) to set the starting frame for recording, and
the number of video frames to record per each subsequent call to record(&cframe).
Both arguments to progmvas are integers (in C, not pointers to integers). The
argument cframe to record is a pointer to an integer.
For each rendered scene in the animation, call record(&cframe) to record
scene as a video frame. Depending on the framesper variable used in the
call to progmvas, the number of video frames recorded will vary. The
argument &cframe is set to the current video frame upon completion of the
