GNUPLOT_CMD

• INPUTS :
  • ptr_gctrl : Pointer to structure of type gnuplot_ctrl.
  • cmd : Character string (command to be executed in the gnuplot session).
• OUTPUTS :
  • status : Integer (error flag).
• PURPOSE :

  Executes a single line of commands in the gnuplot session via a pipe. Its use is generally not recommended. Use it only as a last resort if none of the other functions in the library work for you.

• DIAGNOSTICS :
  • status = 0 : Success.
  • status = BAD_SIGNAL : Called with a dissociated pointer.
  • status = -8888 : Failed to write to pipe.
  • status = -7777 : Command too long for pipe buffer.
  • status = -6666 : Failed to flush the pipe.
• INTERFACE :

  interface integer function gnuplot_cmd(ptr_gctrl,cmd) result(status) type(gnuplot_ctrl), pointer :: ptr_gctrl character(len=*), intent(in) :: cmd end function gnuplot_cmd end interface
