SGSetSoundInputDriver

Some sound channel components may use sound input devices to obtain their source data. The SGSetSoundInputDriver function allows the sequence grabber component to assign a sound input device to your sound channel.

pascal ComponentResult SGSetSoundInputDriver (SGChannel c, 
                                       const Str255 driverName);

c

Identifies the channel connection for this operation.

driverName

Specifies the name of the sound input device. This is a Pascal string, and it must correspond to a valid sound input device.

DESCRIPTION

If your sound channel component does not use sound input devices, return a nonzero result code.

RESULT CODES

noDeviceForChannel	-9400	Channel component cannot find its device
cantDoThatInCurrentMode	-9402	Request invalid in current mode
deviceCantMeetRequest	-9408	Device cannot support grabber
