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.

执行信息

• 多线程类型：可重入（与非独占算子并行运行）。
• 多线程作用域：全局（可从任何线程调用）。
• 未采用并行化处理。

此算子返回一个句柄。请注意，即使该句柄被用作特定算子的输入参数，这些算子仍可能改变此句柄类型的实例状态。

参数

结果

gnuplot_open_pipegnuplot_open_pipeGnuplotOpenPipeGnuplotOpenPipeGnuplotOpenPipegnuplot_open_pipe 返回值 2 ( H_MSG_TRUE) if the sub-process could be created.否则，将抛出异常。
