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

inject getzoneid system call into victim process

Process Control Library (libproc, -lproc)
#include <libproc.h>

pr_getzoneid(struct ps_prochandle *P);

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

The pr_getzoneid() 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_getzoneid() function's return value is that described in getzoneid(3C). Otherwise, -1 is returned and errno 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 getzoneid(3C).

The pr_getzoneid() 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.
