SndChannelStatus

Determine the status of a sound channel

#include <Sound.h> Sound Manager

OSErr SndChannelStatus(chan, theLength, theStatus);

SndChannelPtr chan; a pointer to a valid sound channel

SndCommand theLength; the size in bytes of the status structure

SCStatusPtr theStatus; a pointer to an SCStatus structure

returns Error Code; 0=no error

You can use SndChannelStatus to determine the status of a

Sound Manager sound channel.

chan should be a pointer to a valid sound channel.

theLength should be the size in bytes of the status structure that theStatus

points to.

theStatus should be a pointer to an SCStatus structure. On successful

completion of the call, the fields of that structure contain the

information about the specified sound channel.

Returns: an operating system Error Code.

noErr (0) No error

paramErr (-50) A parameter is incorrect

badChannel (-205) Channel is corrupt or unusable

Notes: You can call SndChannelStatus at interrupt time.

You can obtain information about a sound channel and about the

and SndManagerStatus functions. You can obtain the version numbers of

the Sound Manager, the MACE tools, and the sound input routines by

SPBVersion functions, respectively.
