1 <h1>KERN-EXEC</h1>

     2 <p>

     3 These panics represent program errors which are detected by the Kernel

     4 Executive. Typically, they are caused by passing bad or contradictory

     5 parameters to functions. Threads which cause exceptions also raise a KERN-EXEC

     6 panic. 

     7 </p>

     8 <p>

     9 The thread causing the panic is terminated. 

    10 </p>

    11 <code>0</code>

    12 <p>

    13 This panic is raised when the Kernel cannot find an object in the

    14 object index for the current process or current thread using the specified

    15 object index number (the raw handle number). 

    16 </p>

    17 <p>

    18 The most common reason for this is trying to use a kernel-side

    19 resource without first having sucessfully created it or sucessfully opened it.

    20 Typically, such resources are created or opened through user side handles,

    21 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>,

    22 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>,

    23 <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

    24 this list is not exhaustive].

    25 </p>

    26 <p>

    27 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>

    28 panics with KERN-EXEC 0 if not preceded by a successful call to

    29 <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>. 

    30 </p>

    31 <code>1</code>

    32 <p>

    33 This is a general panic raised as a result of trying an

    34 unauthorised activity such as trying to suspend a thread, to set the priority

    35 of a thread or to set the priority of a process, when not authorised to do so. 

    36 </p>

    37 <code>2</code>

    38 <p>

    39 This panic is raised by the kernel when opening a kernel side

    40 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. 

    41 </p>

    42 <p>

    43 The fullname is deemed to be invalid if it contains a character

    44 that is not one of the printable characters lying between 0x20 and 0x7e

    45 inclusive, or it contains an asterisk or a question mark. 

    46 </p>

    47 <p>

    49 </p>

    50 <code>3</code>

    51 <p>

    52 This panic is raised when an unhandled exception occurs. Exceptions

    53 have many causes, but the most common are access violations caused, for

    54 example, by dereferencing NULL. Among other possible causes are: general

    55 protection faults, executing an invalid instruction, alignment checks, etc.

    66 <p>

    67 This panic is raised by the kernel when a handle to a code segment

    78 <code>9</code>

    79 <p>

    80 This is a general type of panic that is usually raised by a device

    81 driver when dealing with an asynchronous request, and it finds that an

    82 asynchronous request is already outstanding. For an example of the context in

    83 which this is raised, see

    84 <code class="filename">...\cedar\e32test\examples\driver1\driver1_ldd.cpp</code>. 

    85 </p>

    86 <p>

    87 This panic is also raised when trying to subscribe to a property

    88 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

    89 already an outstanding subscription on this property handle. 

    90 </p>

    91 <code>10</code>

    92 <p>

    93 This panic is raised by

    99 </p>

   100 <code>11</code>

   101 <p>

   102 This panic is raised when creating a logical channel, and the unit number is outside the permitted range: 

   103 </p>

   104 <p>

   105 If unit numbers are not permitted, the unit number value must

   106 be <a href="../reference-cpp/E32_EKA2/e32const.hVariables.html#%3a%3aKNullUnit" title="field KNullUnit"><code class="ApiItem">KNullUnit</code></a>. 

   107 </p>

   108 <p>

   109 If unit numbers are permitted, the unit number value must be

   110 less than <a href="../reference-cpp/E32_EKA2/e32const.hVariables.html#%3a%3aKMaxUnits" title="field KMaxUnits"><code class="ApiItem">KMaxUnits</code></a>. 

   111 </p>

   112 <p>

   115 </p>

   116 <code>12</code>

   117 <p>

   118 This panic is raised by the kernel if an event capture hook has already been designated. 

   119 </p>

   120 <code>13</code>

   121 <p>

   122 This panic is raised by the kernel if the current thread is not the designated event capture hook. 

   123 </p>

   124 <code>14</code>

   125 <p>

   126 This panic is raised when an attempt is made to set the priority of

   127 a thread or process to an illegal value. 

   128 </p>

   129 <p>

   130 The permitted priority values for a user process are a subset of

   131 the values defined by the <a href="../reference-cpp/E32_EKA2/TProcessPriorityEnum.html#%3a%3aTProcessPriority" title="enum TProcessPriority"><code class="ApiItem">TProcessPriority</code></a> enum. The

   132 permitted values are:

   198 This panic is raised when a timer event is requested from an

   199 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

   200 is already outstanding. It is caused by calling either the <code>At()</code>,

   201 <code>After()</code> or <code>Lock()</code> member functions after a previous

   202 call to any of these functions, but before the timer event requested by those

   203 functions has completed.

   219 This panic is raised by the Kernel when a server program makes a

   220 request to receive a message, i.e. when it calls the <code>Receive()</code>

   221 member function of <code>RServer2</code>, the handle to the Kernel side server

   222 object. The panic occurs when a receive message request has previously been

   223 made and is still outstanding. 

   224 </p>

   225 <p>

   226 Note that <code>RServer2</code> is internal to Symbian 

   227 </p>

   228 <code>20</code>

   229 <p>

   230 This panic is raised by the Kernel when a request for an event, as

   231 originated by a call to <code>UserSvr::RequestEvent()</code>, defined in

   370 <p>

   371 This panic can be raised as a result of a call to one of a large

   372 number of functions. In general, the panic indicates an attempt to perform an

   373 operation on a thread or process by code running in another process - violating

   374 the security principle of process isolation. 

   375 </p>

   376 <p>

   377 There are exceptions to this general rule, for example, where the

   378 panic is raised because the calling process has insufficient capability. The

   379 precise reason is stated with the function(s). 

   380 </p>

   381 <p>

   382 The panic is raised on a call to the following function if the

   383 process owning the thread performing the call is not the creator of the target

   384 process or, if a handle is specified, the handle is not local.
