Detailed Description

IO stream structure, used for read/write access to OD variable, part of OD_IO_t.

Field Documentation

dataOrig

void* OD_stream_t::dataOrig

Pointer to original data object, defined by Object Dictionary.

Default read/write functions operate on it. If memory for data object is not specified by Object Dictionary, then dataOrig is NULL.

object

void* OD_stream_t::object
