Syntax

events = modifyOrder(c,modorder)
事件= modifyOrder（C，Modorder，'timeOut',timeout)
修改订单（___,'useDefaultEventHandler',false)
___= modifyOrder（C，Modorder，选项）

Description

example

events= modifyOrder(c,modorder)修改彭博社®EMSX order using the Bloomberg EMSX connectionc和modify order request structuremodorder。modifyOrder使用默认事件处理程序返回状态消息。

example

events= modifyOrder(c,modorder,'timeOut',timeout)specifies a timeout valuetimeoutfor the execution of the default event handler.

example

修改订单（___,'useDefaultEventHandler',false)使用上一个语法和自定义事件处理程序中的任何输入参数修改彭博社EMSX订单。编写一个自定义事件处理程序来处理与修改订单相关的事件。该语法没有输出参数，因为自定义事件处理程序处理事件队列的内容。如果要使用默认事件处理程序，请设置标志“ underefeaulteventhandler”to真的和use theeventsoutput argument. By default, the flag“ underefeaulteventhandler”被设定为真的。

example

___= modifyOrder(c,modorder,options)uses theoptions自定义输出的结构，这对于预配置很有用，并保存您的选项以重复使用。可用options结构体fields aretimeOut和UsedefaultEventHandler。利用theeventsoutput argument when the flagUsedefaultEventHandler被设定为真的和omit this output argument whenUsedefaultEventHandler被设定为false。

Data Types:struct

超时值，指定为非负整数。该整数表示时间为毫秒的时间，即事件处理程序听代码的每次迭代的事件队列。事件处理程序可以是默认或自定义事件处理程序。

Data Types:double

Options for a custom event handler or timeout value, specified as a structure. To reuse the settings for specifying a custom event handler or timeout value for the event handler, use theoptions结构体。

For example, specify using a custom event handler and a timeout value of 200 milliseconds.

options.useDefaultEventHandler = false; options.timeOut = 200;

Data Types:struct

Output Arguments

collapse all

Event queue contents, returned as a double or structure.

If the event queue contains events,events是包含事件队列的当前内容的结构。否则，eventsis an empty double.
