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

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:

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.
