DOCERR: Minimal SDK Profiler Functions Required

 * }

Q90791

-

The information in this article applies to:


 * Microsoft Windows Software Development Kit (SDK) 3.1

-

SYMPTOMS
The directions given in Chapter 10 of the Windows 3.1 SDK &quot;Programming Tools&quot; manual are followed, but no profiler output is generated.

CAUSE
The &quot;Programming Tools&quot; manual states the following on page 208:


 * 1) Include in your application at least the two mandatory Profiler functions ProfStart and ProfStop.

ProfStart indicates when you want Profiler to start sampling code; ProfStop indicates when you want Profiler to stop sampling. Other Profiler functions are optional.

This is accurate but not complete. ProfStop does stop sampling, but it does not write any output to the disk. Because of this, the Profiler appears to not work.

RESOLUTION
To get the Profiler to function completely, either a call to the Profiler function ProfFlush must be made prior to the call to ProfStop, or the function ProfFinish should be used. The documentation would be more accurate if it stated that the minimum Profile application contained a call to ProfStart and a call to ProfFinish. ProfFinish stops profile sampling and flushes the buffer (to disk).
