Discussion

The GetSpeechInfo functionreturns, in the data structure pointed to by the speechInfo parameter,the type of information requested by the selector parameteras it applies to the speech channel specified in the chan parameter.

The format of the data structure specified by the speechInfo parameterdepends on the selector you choose. For example, a selector mightrequire that your application allocate a block of memory of a certainsize and pass a pointer to that block. Another selector might requirethat speechInfo be setto the address of a handle variable. In this case, the GetSpeechInfo functionwould allocate a relocatable block of memory and change the handlevariable specified to reference the block.
