<h1>KERN-EXEC</h1>
<p>
These panics represent program errors which are detected by the Kernel
Executive. Typically, they are caused by passing bad or contradictory
parameters to functions. Threads which cause exceptions also raise a KERN-EXEC
panic. 
</p>
<p>
The thread causing the panic is terminated. 
</p>
<code>0</code>
<p>
This panic is raised when the Kernel cannot find an object in the
object index for the current process or current thread using the specified
object index number (the raw handle number). 
</p>
<p>
The most common reason for this is trying to use a kernel-side
resource without first having sucessfully created it or sucessfully opened it.
Typically, such resources are created or opened through user side handles,
which are instances of classes derived from <a href="../reference-cpp/E32_EKA2/RHandleBaseClass.html#%3a%3aRHandleBase" title="class RHandleBase"><code class="ApiItem">RHandleBase</code></a>,
for example, <a href="../reference-cpp/E32_EKA2/RLibraryClass.html#%3a%3aRLibrary" title="class RLibrary"><code class="ApiItem">RLibrary</code></a>, <a href="../reference-cpp/E32_EKA2/RThreadClass.html#%3a%3aRThread" title="class RThread"><code class="ApiItem">RThread</code></a>,
<a href="../reference-cpp/E32_EKA2/RProcessClass.html#%3a%3aRProcess" title="class RProcess"><code class="ApiItem">RProcess</code></a>, <a href="../reference-cpp/E32_EKA2/RSemaphoreClass.html#%3a%3aRSemaphore" title="class RSemaphore"><code class="ApiItem">RSemaphore</code></a> etc. [Note that
this list is not exhaustive].
</p>
<p>
For example, a call to <a href="../reference-cpp/E32_EKA2/RLibraryClass.html#%3a%3aRLibrary%3a%3aLookup%28%29" title="function RLibrary::Lookup()"><code class="ApiItem">RLibrary::Lookup()</code></a>
panics with KERN-EXEC 0 if not preceded by a successful call to
<a href="../reference-cpp/E32_EKA2/RLibraryClass.html#%3a%3aRLibrary%3a%3aLoad%28%29" title="function RLibrary::Load()"><code class="ApiItem">RLibrary::Load()</code></a>. 
</p>
<code>1</code>
<p>
This is a general panic raised as a result of trying an
unauthorised activity such as trying to suspend a thread, to set the priority
of a thread or to set the priority of a process, when not authorised to do so. 
</p>
<code>2</code>
<p>
This panic is raised by the kernel when opening a kernel side
object, a <a href="../reference-cpp/E32_EKA2/DObjectClass.html#%3a%3aDObject" title="class DObject"><code class="ApiItem">DObject</code></a> type, and the fullname is invalid. 
</p>
<p>
The fullname is deemed to be invalid if it contains a character
that is not one of the printable characters lying between 0x20 and 0x7e
inclusive, or it contains an asterisk or a question mark. 
</p>
<p>

</p>
<code>3</code>
<p>
This panic is raised when an unhandled exception occurs. Exceptions
have many causes, but the most common are access violations caused, for
example, by dereferencing NULL. Among other possible causes are: general
protection faults, executing an invalid instruction, alignment checks, etc.

</p>
<code>5</code>

</p>
<code>6</code>
<p>
This panic is raised by the kernel when a handle to a code segment
is invalid. 
</p>

<p>
This panic is not used. 
</p>
<code>8</code>
<p>
This panic is not used. 
</p>
<code>9</code>
<p>
This is a general type of panic that is usually raised by a device
driver when dealing with an asynchronous request, and it finds that an
asynchronous request is already outstanding. For an example of the context in
which this is raised, see
<code class="filename">...\cedar\e32test\examples\driver1\driver1_ldd.cpp</code>. 
</p>
<p>

through a call to <a href="../reference-cpp/E32_EKA2/RPropertyClass.html#%3a%3aRProperty%3a%3aSubscribe%28%29" title="function RProperty::Subscribe()"><code class="ApiItem">RProperty::Subscribe()</code></a> and there is
already an outstanding subscription on this property handle. 
</p>
<code>10</code>
<p>
This panic is raised by
<a href="../reference-cpp/E32_EKA2/DLogicalChannelClass.html#%3a%3aDLogicalChannel%3a%3aRequest%28%29" title="function DLogicalChannel::Request()"><code class="ApiItem">DLogicalChannel::Request()</code></a> when the request number passed

</p>
<code>11</code>
<p>
This panic is raised when creating a logical channel, and the unit number is outside the permitted range: 
</p>
<p>
If unit numbers are not permitted, the unit number value must
be <a href="../reference-cpp/E32_EKA2/e32const.hVariables.html#%3a%3aKNullUnit" title="field KNullUnit"><code class="ApiItem">KNullUnit</code></a>. 
</p>

</p>

A logical channel is created as a result of a call to
<a href="../reference-cpp/E32_EKA2/RBusLogicalChannelClass.html#%3a%3aRBusLogicalChannel%3a%3aDoCreate%28%29" title="function RBusLogicalChannel::DoCreate()"><code class="ApiItem">RBusLogicalChannel::DoCreate()</code></a>. 
</p>
<code>12</code>
<p>
This panic is raised by the kernel if an event capture hook has already been designated. 
</p>
<code>13</code>
<p>
This panic is raised by the kernel if the current thread is not the designated event capture hook. 
</p>
<code>14</code>
<p>
This panic is raised when an attempt is made to set the priority of
a thread or process to an illegal value. 
</p>

asynchronous timer service, an <a href="../reference-cpp/E32_EKA2/RTimerClass.html#%3a%3aRTimer" title="class RTimer"><code class="ApiItem">RTimer</code></a>, and a timer event
is already outstanding. It is caused by calling either the <code>At()</code>,

functions has completed. 
</p>

request to receive a message, i.e. when it calls the <code>Receive()</code>
member function of <code>RServer2</code>, the handle to the Kernel side server
object. The panic occurs when a receive message request has previously been
made and is still outstanding. 
</p>
<p>
Note that <code>RServer2</code> is internal to Symbian 
</p>

<p>
This panic is raised by the Kernel when a request for an event, as

member of the base class <a href="../reference-cpp/E32_EKA2/RHandleBaseClass.html#%3a%3aRHandleBase" title="class RHandleBase"><code class="ApiItem">RHandleBase</code></a> has become corrupt. 
</p>
<code>45</code>
<p>
This panic is not used. 
</p>
<code>46</code>
<p>
This panic can be raised as a result of a call to one of a large
number of functions. In general, the panic indicates an attempt to perform an
operation on a thread or process by code running in another process - violating
the security principle of process isolation. 
</p>
<p>
There are exceptions to this general rule, for example, where the
panic is raised because the calling process has insufficient capability. The
precise reason is stated with the function(s). 
</p>
<p>
The panic is raised on a call to the following function if the
process owning the thread performing the call is not the creator of the target
process or, if a handle is specified, the handle is not local. 
</p>
<p>
<a href="../reference-cpp/E32_EKA2/RProcessClass.html#%3a%3aRProcess%3a%3aSetParameter%28%29" title="function RProcess::SetParameter()"><code class="ApiItem">RProcess::SetParameter()</code></a>

process owning the thread performing the call is not the same as the target
process.

<p>
NOTE: the creator of a new process can kill or panic the new
process, change the new process priority and set the new process startup
parameters until the process is resumed (which the creator can also do). After
the new process has been resumed, then it becomes totally independent of its
creator, and any attempt to panic it, kill it etc will raise the KERN-EXEC 46
panic.
