1 | <h2>task_get_emulation_vector</h2> |
2 | <hr> | |
3 | <p> | |
4 | <strong>Function</strong> - Return an array identifying the target task's user-level system call handlers. | |
5 | <h3>SYNOPSIS</h3> | |
6 | <pre> | |
7 | <strong>kern_return_t task_get_emulation_vector</strong> | |
8 | <strong>(task_t</strong> <var>task</var>, | |
9 | <strong>int</strong> <var>vector_start</var>, | |
10 | <strong>emulation_vector_t</strong> <var>emulation_vector</var>, | |
11 | <strong>mach_msg_type_number_t*</strong> <var>emulation_vector_count</var><strong>);</strong> | |
12 | </pre> | |
13 | <h3>PARAMETERS</h3> | |
14 | <dl> | |
15 | <p> | |
16 | <dt> <var>task</var> | |
17 | <dd> | |
18 | [in task send right] | |
19 | The port for the task for which the system call | |
20 | handler addresses are desired. | |
21 | <p> | |
22 | <dt> <var>vector_start</var> | |
23 | <dd> | |
24 | [out scalar] | |
25 | The syscall number corresponding to the first element of | |
26 | <var>emulation_vector</var>. | |
27 | <p> | |
28 | <dt> <var>emulation_vector</var> | |
29 | <dd> | |
30 | [out pointer to dynamic array of <strong>vm_address_t</strong>] | |
31 | Pointer to the returned | |
32 | array of routine entrypoints for the system calls starting with syscall | |
33 | number <var>vector_start</var>. | |
34 | <p> | |
35 | <dt> <var>emulation_vector_count</var> | |
36 | <dd> | |
37 | [out scalar] | |
38 | The number of entries filled by the kernel. | |
39 | </dl> | |
40 | <h3>DESCRIPTION</h3> | |
41 | <p> | |
42 | The <strong>task_get_emulation_vector</strong> function returns the | |
43 | user-level syscall handler entrypoint addresses. | |
44 | <h3>NOTES</h3> | |
45 | <p> | |
46 | This interface is machine word length specific because of the | |
47 | virtual addresses in the <var>emulation_vector</var> parameter. | |
48 | <h3>RETURN VALUES</h3> | |
49 | <p> | |
50 | Only generic errors apply. | |
