PR_GETPEERNAME(3PROC) Process Control Library Functions
pr_getpeername - inject getpeername library call into victim process
Process Control Library (libproc, -lproc)
#include <libproc.h>
int
pr_getpeername(struct ps_prochandle *P, int sock,
struct sockaddr *name, socklen_t *namelen);
The pr_getpeername() function injects the getpeername(3SOCKET) library
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
getpeername(3SOCKET) on the currently running process.
The arguments sock, name, and namelen have the same meaning as in
getpeername(3SOCKET). See getpeername(3SOCKET) for the full
description and purpose of the getpeername library call and its
arguments.
The pr_getpeername() function only works on active processes. Process
handles that correspond to core files, zombie processes, or ELF objects
do not support library call injection.
Upon successful completion, the pr_getpeername() function's return
value is that described in getpeername(3SOCKET). Otherwise, -1 is
returned and errno is set to ENOSYS to indicate that the library call
could not be injected.
For the full list of errors see the ERRORS section in
getpeername(3SOCKET).
The pr_getpeername() function will fail if:
ENOSYS An error occurred while trying to invoke the agent
LWP and inject a library call in the process handle
P or the process handle P does not support library
call injection.
