<h2>Synopsis</h2>
|
|
|
|
<p />These functions are used to get some runtime information
|
|
from the Just in Time compiler and also to control some
|
|
aspects of the initialization and shutdown of the runtime.

<h3>Just-in-Time Compiled Method Information</h3>
|
|
|
|
<p />Use the `MonoJitInfo` API to get data about a JITed
|
|
method. These APIs are typically used by profiler modules
|
|
added to Mono.

|
|
Use this function to obtain a <code>MonoJitInfo*</code> object that can be used to get
|
|
some statistics. You should provide both the <i>domain</i> on which you will be
|
|
performing the probe, and an address. Since application domains can share code
|
|
the same address can be in use by multiple domains at once.
|
|
<p />
|
|
This does not return any results for trampolines.
