描述

gnuplot_open_pipegnuplot_open_pipeGnuplotOpenPipeGnuplotOpenPipeGnuplotOpenPipegnuplot_open_pipe opens a pipe to a gnuplot sub-process with which subsequently images can be visualized as 3D-plots (gnuplot_plot_imagegnuplot_plot_imageGnuplotPlotImageGnuplotPlotImageGnuplotPlotImagegnuplot_plot_image) or control values can be visualized as 2D-plots (gnuplot_plot_ctrlgnuplot_plot_ctrlGnuplotPlotCtrlGnuplotPlotCtrlGnuplotPlotCtrlgnuplot_plot_ctrl). The sub-process must be terminated after displaying the last plot by calling gnuplot_closegnuplot_closeGnuplotCloseGnuplotCloseGnuplotClosegnuplot_close. The corresponding identifier for the gnuplot output stream is returned in GnuplotFileIDGnuplotFileIDGnuplotFileIDGnuplotFileIDgnuplotFileIDgnuplot_file_id.

注意

gnuplot_open_pipegnuplot_open_pipeGnuplotOpenPipeGnuplotOpenPipeGnuplotOpenPipegnuplot_open_pipe is only implemented for Unix-like systems because gnuplot for Windows (wgnuplot) cannot be controlled by an external process.

运行信息

• 多线程类型:可重入(与非独占操作符并行运行)。
• 多线程作用域:全局(可以从任何线程调用)。
• 未经并行化处理。

This operator returns a handle. Note that the state of an instance of this handle type may be changed by specific operators even though the handle is used as an input parameter by those operators.

结果

gnuplot_open_pipegnuplot_open_pipeGnuplotOpenPipeGnuplotOpenPipeGnuplotOpenPipegnuplot_open_pipe 返回值 2 ( H_MSG_TRUE) if the sub-process could be created. Otherwise, an exception is raised.
