Miles Sound System SDK 7.2a

Call Logging under DOS

Discussion

Miles contains a powerful diagnostic feature that allows developers to create a timestamped list of all of their application's foreground Miles calls, along with their parameters and results. The call log will be sent to an application callback routine registered with AIL_register_trace_callback, or to a plain text file if no debug-trace callback function has been registered by the application.

To take advantage of MSS's built-in logging without recompiling your application, set the DOS environment variable "MSS_DEBUG" to a filename to write the log to. During execution of all subsequent Miles calls, a timestamped API call log will be written to the specified file.

For example, to dump the API call log to a file name foo.txt, execute the following command at the DOS prompt:

set MSS_DEBUG=foo.txt

You can also view MSS's internal function calls by running the extra command, "set MSS_SYS_DEBUG=1".
