* Gets all register values in the target thread with pointer-like contents.
|
|
*
|
|
* There is no guarantee that the returned values are valid pointers, but all
|
|
* valid pointers will be returned. The order and count of the provided
|
|
* register values is unspecified and may change; registers with values that
|
|
* are not valid pointers may be omitted, so the number of pointers returned
|
|
* may vary from call to call.
|

*
|
|
* sp is an out parameter that will contain the stack pointer.
|
|
* length is an in/out parameter for the length of the values array.
|
|
* values is an array of pointers.
|
|
*
|
|
* This may only be called on threads in the current task. If the current
|
|
* platform defines a stack red zone, the stack pointer returned will be
|
|
* adjusted to account for red zone.
|
|
*
|
|
* If length is insufficient, KERN_INSUFFICIENT_BUFFER_SIZE will be returned
|
|
* and length set to the amount of memory required. Callers MUST NOT assume
|
|
* that any particular size of buffer will be sufficient and should retry with
|
|
* an appropriately sized buffer upon this error.
