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

pr_linkinject link system call into victim process

Process Control Library (libproc, -lproc)

#include <libproc.h>

int
pr_link(struct ps_prochandle *P, const char *existing, const char *new);

The () function injects the link(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 link(2) on the currently running process.

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_link() function's return value is that described in link(2). Otherwise, is returned and is set to ENOSYS to indicate that the system call could not be injected.

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

The pr_link() 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).
