The \fIgflush\fR task disposes of any buffered graphics +output and also initializes the graphics subsystem. The cursor mode frame +buffer is cleared, any connected graphics subkernels are disconnected, +and the memory and file descriptors used by the graphics subsystem are +freed. A \fIgflush\fR occurs automatically upon logout from the CL. + +The number of frames (plots) the graphics system will buffer for a device +is controlled by the MF (multi-frame) parameter in the \fIgraphcap\fR entry +for the device. When the multi-frame count is reached the buffered output +is automatically disposed of to the device. +.ih +EXAMPLES +1. Flush any graphics output and initialize the graphics system. + + cl> gflush +.ih +SEE ALSO +cursor, stdplot |
