PR_CREAT(3PROC) Process Control Library Functions PR_CREAT(3PROC)

NAME


pr_exit - inject exit system call into victim process

SYNOPSIS


Process Control Library (libproc, -lproc)
#include <libproc.h>

int
pr_exit(struct ps_prochandle *P, int status);

DESCRIPTION


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

The argument status has the same meaning as in exit(2). See exit(2) for
the full description and purpose of the exit system call and its arguments.

The pr_exit() 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_exit() function's return value is that
described in exit(2). Otherwise, -1 is returned and errno is set to ENOSYS
to indicate that the system call could not be injected.

If the pr_exit() function is called with the value of P set to NULL, then
the function will not return.

ERRORS


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

The pr_exit() 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
