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

pr_door_infoinject door_info library call into victim process

Process Control Library (libproc, -lproc)

#include <libproc.h>

int
pr_door_info(struct ps_prochandle *P, int did, struct door_info *info);

The () function injects the door_info(3C) 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 door_info(3C) on the currently running process.

The arguments did and info have the same meaning as in door_info(3C). See door_info(3C) for the full description and purpose of the library 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 library call injection.

Upon successful completion, the pr_door_info() function's return value is that described in door_info(3C). Otherwise, is returned and 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 door_info(3C).

The pr_door_info() 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.

See in libproc(3LIB).
