- Specifies the connection to the Y server, obtained by a call to YOpenConnection.
- Specifies the pointer to the sound buffer on the Y server that was obtained by a call to YSHMOpenSound.
The YSHMCloseSound closes a direct pointer to the sound buffer on the Y server. The pointer ptr must have been obtained by a prior call to YSHMOpenSound.
If you receive a YSHMSound event with the minor_op_code set to YSHMSoundClose then the pointer to the sound buffer obtained from YSHMOpenSound is no longer referenced by the Y server and is now useless. You need to reopen the buffer by calling YSHMCloseSound and then YSHMOpenSound to reobtain the direct pointer to the sound buffer on the Y server.
The process of the client and the server must both be running on the same physical machine.
