Example for retrieve buffer size of bin file via ostream* pointer

[Annie834]

I am intented to get buffer size from ostream, after performing the method "GetBufferStream"

std::string bufferStr; for (auto ele : doc.bufferViews.Elements()) { // std::stringstream std::ostream* ostrem = glbResourceWriter->GetBufferStream(ele.id); (*ostrem) << bufferStr; bufferStr += bufferStr; } bin_out.append(bufferStr.data(), bufferStr.data() + bufferStr.length());

the issue is that value of bufferStr is awalys empty or null, therefore, it is impossible to calculate the buffer size and data from the bufferStr.

the screenshot of result:

it's appreciated if you can reply my question.
