-<h2>task_set_emulation_vector</h2>
-<hr>
-<p>
-<strong>Function</strong> - Establish the target task's user-level system call handlers.
-<h3>SYNOPSIS</h3>
-<pre>
-<strong>kern_return_t task_set_emulation_vector</strong>
- <strong>(task_t</strong> <var>task</var>,
- <strong>int</strong> <var>vector_start</var>,
- <strong>emulation_vector_t</strong> <var>emulation_vector</var>,
- <strong>mach_msg_type_number_t</strong> <var>emulation_vector_count</var><strong>);</strong>
-</pre>
-<h3>PARAMETERS</h3>
-<dl>
-<p>
-<dt> <var>task</var>
-<dd>
-[in task send right]
-The port for the task for which to establish the
-system call handler.
-<p>
-<dt> <var>vector_start</var>
-<dd>
-[in scalar]
-The syscall number corresponding to the first element of
-<var>emulation_vector</var>.
-<p>
-<dt> <var>emulation_vector</var>
-<dd>
-[pointer to in array of <strong>vm_address_t</strong>]
-An array of routine entrypoints
-for the system calls starting with syscall number <var>vector_start</var>.
-<p>
-<dt> <var>emulation_vector_count</var>
-<dd>
-[in scalar]
-The number of elements in <var>emulation_vector</var>.
-</dl>
-<h3>DESCRIPTION</h3>
-<p>
-The <strong>task_set_emulation_vector</strong> function establishes
-a handler within the task
-for a set of system calls. When a thread executes a system call
-with one of these
-numbers, the system call will be redirected to the corresponding
-routine within
-the task's address space.
-<p>
-These emulation handler addresses are inherited by child processes.
-<h3>NOTES</h3>
-<p>
-This interface is machine word length specific because of the
-virtual addresses
-in the <var>emulation_vector</var> parameter.
-<h3>RETURN VALUES</h3>
-<p>
-Only generic errors apply.
