man YSHMCloseSound (Fonctions bibliothèques) - shared sound buffer closing
NAME
YSHMCloseSound - shared sound buffer closing
SYNTAX
#include <Y2/Y.h>
#include <Y2/Ylib.h>
void YSHMCloseSound(
YConnection *connection,
void *ptr
)
ARGUMENTS
- connection
- Specifies the connection to the Y server, obtained by a call to YOpenConnection.
- ptr
- Specifies the pointer to the sound buffer on the Y server that was obtained by a call to YSHMOpenSound.
DESCRIPTION
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.
EXAMPLE
#include <stdio.h>
#include <Y2/Y.h>
#include <Y2/Ylib.h>
int main(int argc, char *argv[])
{
int length, id;
void *buf;
YConnection *con = YOpenConnection(
"/usr/sbin/starty",
"127.0.0.1:9433"
);
if(con == NULL)
return(1);
/* Obtain the pointer to the sound buffer. */
buf = YSHMOpenSound(con, &length, &id);
if(buf != NULL)
{
/* Do something with the buffer here. */
/* Close the pointer to the sound buffer. */
YSHMCloseSound(con, buf);
}
YCloseConnection(con, False);
return(0);
