GpaEndSample
Syntax
Copied!
GpaStatus GpaEndSample(
GpaCommandListId command_list_id);
Description
Ends a sample in a command list. A sample is a particular workload for which counters will be collected. If the owning session was created with kGpaSessionSampleTypeDiscreteCounter and one or more counters have been enabled, then those counters will be collected for this sample. Each sample must be associated with a GPA command list. Samples can be created by using multiple threads provided no two threads are creating samples on same command list. You must provide a unique Id for every new sample. You may create as many samples as needed. However, nesting of samples is not allowed. Each sample must be wrapped in sequence of GpaBeginSample/GpaEndSample before starting another one. A sample can be started in one primary command list and continued/ended on another primary command list – See GpaContinueSampleOnCommandList.
