SaveInstanceTreeA

This function saves the selected instance and its dependencies in an array.

Syntax

C++ 32 bit
C++ 64 bit
C# 32 bit
C# 64 bit
public const string enginedll = @"engine.dll";

[DllImport(enginedll, EntryPoint = "SaveInstanceTreeA")]
public static extern Int64 SaveInstanceTreeA(Int64 owlInstance, byte[] content, out Int64 size);

Property owlInstance

Size: 64 bit / 8 byte (value)
The handle to the specific instance in the design tree. The instance handle is static within one open model but is most probably different when the same instance is opened in another model. The instance is always exactly of one unique class.

Property content

Size: 32 bit / 4 byte (reference)
The content of this IO call, the size of the content is defined by attribute size.

Property size

Size: 32 bit / 4 byte (reference)
The size of the content as defined in number of bytes.
