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
See LOCKING in libproc(3LIB).
