17.Sh NAME
18.Nm pr_processor_bind
19.Nd inject processor_bind system call into victim process
20.Sh SYNOPSIS
21.Lb libproc
22.In libproc.h
23.Ft int
24.Fo pr_processor_bind
25.Fa "struct ps_prochandle *P"

31.Sh DESCRIPTION
32The
33.Fn pr_processor_bind
34function injects the
35.Xr processor_bind 2
36system call into the target process
37.Fa P
38by means of the agent LWP.
39If the process handle
40.Fa P
41is the value
42.Dv NULL
43then this will be equivalent to calling
44.Xr processor_bind 2
45on the currently running process.
46.Pp
47The arguments
48.Fa idtype ,
49.Fa id ,
50.Fa processorid ,
51and
52.Fa obind
53have the same meaning as in
54.Xr processor_bind 2 .
55See
56.Xr processor_bind 2
57for the full description and purpose of the
58.Sy processor_bind
59system call and its arguments.
60.Pp
61The
62.Fn pr_processor_bind
63function only works on active processes. Process handles that correspond
64to core files, zombie processes, or ELF objects do not support system
65call injection.
66.Sh RETURN VALUES
67Upon successful completion, the
68.Fn pr_processor_bind
69function's return value is that described in
70.Xr processor_bind 2 .
71Otherwise,
72.Sy -1
73is returned and
74.Sy errno
75is set to
76.Er ENOSYS
77to indicate that the system call could not be injected.
78.Sh ERRORS
79For the full list of errors see the
80.Sy ERRORS
81section in
82.Xr processor_bind 2 .
83.Pp
84The
85.Fn pr_processor_bind
86function will fail if:
87.Bl -tag -width Er
88.It Er ENOSYS
89An error occurred while trying to invoke the agent LWP and inject a
90system call in the process handle
91.Fa P
92or the process handle
93.Fa P
94does not support system call injection.
