PR_GETPROJID(3PROC) Process Control Library Functions PR_GETPROJID(3PROC)
NAME
pr_getprojid - inject getprojid system call into victim process
LIBRARY
Process Control Library (libproc, -lproc)
SYNOPSIS
#include <libproc.h> projid_t pr_getprojid(
struct ps_prochandle *P);
DESCRIPTION
The
pr_getprojid() function injects the
getprojid(2) system 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
getprojid(2) on the currently
running process.
The
pr_getprojid() function only works on active processes. Process
handles that correspond to core files, zombie processes, or ELF objects do
not support system call injection.
RETURN VALUES
Upon successful completion, the
pr_getprojid() function's return value is
that described in
getprojid(2). Otherwise,
-1 is returned and
errno is set
to ENOSYS to indicate that the system call could not be injected.
ERRORS
For the full list of errors see the
ERRORS section in
getprojid(2).
The
pr_getprojid() function will fail if:
ENOSYS 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.
