GenApi_GetIntegerDescriptor


Header: Genicam.h
Namespace: avl
Module: Genicam

Reads named integer parameter attributes from GenICam IInteger interface.

Syntax

C++
C#
 
void avl::GenApi_GetIntegerDescriptor
(
	GenApiHandle inHandle,
	const char* inParameterName,
	GenApi_IntegerDescriptor& outDescriptor
)

Parameters

Name Type Default Description
Input value inHandle GenApiHandle Handle to object providing GenApi interface.
Input value inParameterName const char* Textual name of the parameter that should be accessed in GenICam naming convention or device specific name. Parameter name is case sensitive.
Output value outDescriptor GenApi_IntegerDescriptor&

Description

This function accesses the configuration of a device or software module using the GenICam GenApi interface. The actual GenApi interface is accessed through the handle of opened device or software module provided by other subsystem (like opened GigEVision device handle). A call to this function may result in time expensive (blocking) data exchange with device.

This function can be used to obtain additional information of named Integer parameter, like its range and allowed increment. The information is returned using GenApi_IntegerDescriptor structure.

Exceptions

This function will throw an exception in the following situations:

  • Object handle is invalid or does not provide the GenApi interface.
  • GenApi description does not provide a parameter with specified name.
  • Named parameter does not provide the IInteger interface.
  • Connection with device is lost.
  • Other unexpected GenICam or connection error occurred.
