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

pr_exitinject exit system call into victim process

Process Control Library (libproc, -lproc)

#include <libproc.h>

pr_exit(struct ps_prochandle *P, int status);

The () 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 system call and its arguments.

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

Upon successful completion, the pr_exit() function's return value is that described in exit(2). Otherwise, is returned and 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.

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

The pr_exit() function will fail if:

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.

See in libproc(3LIB).
