PR_PROCESSOR_BIND(3PROC) Process Control Library Functions

NAME

pr_processor_bind - inject processor_bind system call into victim
process

LIBRARY

Process Control Library (libproc, -lproc)

SYNOPSIS

#include <libproc.h>

int
pr_processor_bind(struct ps_prochandle *P, idtype_t idtype, id_t id,
int processorid, int *obind);

DESCRIPTION

The pr_processor_bind() function injects the processor_bind(2) system
call into the target process P by means of the agent LWP. If the
process handle P is the value NULL then this will be equivalent to
calling processor_bind(2) on the currently running process.

The arguments idtype, id, processorid, and obind have the same meaning
as in processor_bind(2). See processor_bind(2) for the full
description and purpose of the processor_bind system call and its
arguments.

The pr_processor_bind() function only works on active processes.
Process handles that correspond to core files, zombie processes, or ELF
objects do not support system call injection.

RETURN VALUES

Upon successful completion, the pr_processor_bind() function's return
value is that described in processor_bind(2). Otherwise, -1 is
returned and errno is set to ENOSYS to indicate that the system call
could not be injected.

ERRORS

For the full list of errors see the ERRORS section in
processor_bind(2).

The pr_processor_bind() function will fail if:

ENOSYS An error occurred while trying to invoke the agent
LWP and inject a system call in the process handle P
or the process handle P does not support system call
injection.

INTERFACE STABILITY

Uncommitted

MT-LEVEL
