h1. {anchor:CHP-FASTTRAP} {{fasttrap}} Provider
The {{fasttrap}} provider allows for tracing at specific, preprogrammed user process locations. Unlike most other DTrace providers, the {{fasttrap}} provider is not designed for tracing system activity Rather, this provider is meant as a way for DTrace consumers to inject information into the DTrace framework by activating the {{fasttrap}} probe.
[Top|#top]
h2. {anchor:CHP-FASTTRAP-3} Probes
The {{fasttrap}} provider makes available a single probe, {{fasttrap:::fasttrap}}, that fires whenever a user-level process makes a certain DTrace call into the kernel. The DTrace call to activate the probe is not publicly available at the present time.

h2. {anchor:CHP-FASTTRAP-STABILITY} Stability
The {{fasttrap}} provider uses DTrace's stability mechanism to describe its stabilities, as shown in the following table. For more information about the stability mechanism, see [Chapter 39, Stability|Stability].
