Subject: Incorrect work of sox_open_memstream_write with memstream buffer and buffersize
Date: Fri, 23 Jul 2021 01:43:36 +0000 [thread overview]
Message-ID: <OS3PR01MB5976D18BA9DA7B8114F1E583C1E59@OS3PR01MB5976.jpnprd01.prod.outlook.com> (raw)

Opened by sox_open_memstream_write function，the buffer and buffersize will work incorrectly when seeking back。
For example， when opening buffer with sox_open_memstream_write to get a wav format output，wav handler's stopwrite function will seek back to the beginning to rewrite wav header. In this situation，after closing ft，I assume that I can get whole data from buff and buffsize，but I can only get the wav header.
I don't think it would be better to have seek back to the end when you need to rewrite data with a seek operation.
