描述
control_io_interfacecontrol_io_interfaceControlIoInterfaceControlIoInterfaceControlIoInterfacecontrol_io_interface performs an action on the I/O
interface. The supported parameters are interface-specific and
listed in the corresponding documentation of the used I/O interface
that can be found in the directory doc/html/reference/io.
The special value 'keep_open'"keep_open""keep_open""keep_open""keep_open""keep_open" for ActionActionActionActionactionaction is used to
control when the interface should be unloaded. If ArgumentArgumentArgumentArgumentargumentargument is set
to 'true'"true""true""true""true""true", the interface will remain loaded until the HALCON
process is terminated. If it is set to 'false'"false""false""false""false""false", the interface will
be unloaded as soon as all its device instances are closed. This is the
default behavior.
注意
On Windows Systems, error dialog boxes from the operating system can occur
when dependency modules of the interface are not found, e.g., the according
SDK was not installed. The occurrence of the error boxes can be controlled by
setting Windows' Error Mode. Please refer to the description of SetErrorMode
within the Windows MSDN documentation.
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。
