Parameters

targetBufferObject

Type: OIV.Inventor.Devices.SoBufferObject

The buffer object which will be the mapped version of this buffer.

accessMode

Type: OIV.Inventor.Devices.SoBufferObject.AccessModes

The access mode used for the mapping.

startPosition

Type: System.UInt64

Offset (in bytes) in source buffer to map from (default is start of buffer).

mappingSize

Type: System.UInt64

Size (in bytes) from the startPosition, if SO_BUFFER_SIZE_ALL then the whole buffer is mapped.

This is useful in order to use a buffer in multiple contexts. The default is to map the entire contents of this buffer, but it is also possible to map a subset of this buffer's memory using the startPosition and mappingSize parameters.

A source buffer may be mapped into multiple target buffers. However a target buffer can only be mapped from one source buffer at a time. If a different source buffer is currently mapped into the target buffer, it is automatically unmapped and may be left in an undefined state.

Note: If the current buffer is empty or startPosition is beyond the end of the managed memory, the buffer is not mapped (and an error message is issued in debug builds).
