<strong>Function</strong> - Return an array identifying the target task's user-level system call handlers. 
<strong>kern_return_t   task_get_emulation_vector</strong>
                <strong>(task_t</strong>                                    <var>task</var>,
                 <strong>int</strong>                               <var>vector_start</var>,

<dt> <var>task</var> 
[in task send right]
The port for the task for which the system call
handler addresses are desired.
<dt> <var>vector_start</var> 
[out scalar]
The syscall number corresponding to the first element of 
<dt> <var>emulation_vector</var> 
[out pointer to dynamic array of <strong>vm_address_t</strong>]
Pointer to the returned 
array of routine entrypoints for the system calls starting with syscall 
number <var>vector_start</var>.
<dt> <var>emulation_vector_count</var> 
[out scalar]
The number of entries filled by the kernel.
The <strong>task_get_emulation_vector</strong> function returns the
user-level syscall handler entrypoint addresses.
This interface is machine word length specific because of the
virtual addresses in the <var>emulation_vector</var> parameter.
Only generic errors apply.
