The SndControl function sends control commands directly to a synthesizer

specified by its resource ID. This can be called even if no channel has been

created for the synthesizer. This control function is used with availableCmd or

versionCmd to request information about a synthesizer. You can also use the

totalLoadCmd and loadCmd commands with SndControl to determine the

sound-related CPU load factor. The requested information is returned in the

cmd parameter.

id specifies a resource

cmd is the specific control command

Returns: an operating system Error Code.

noErr (0) No error

Notes: You can not call SndControl at interrupt time because it may need to load

a resource into memory.

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.
