PR_SETTASKID(3PROC) Process Control Library Functions PR_SETTASKID(3PROC)
- inject settaskid system call into victim process
Process Control Library (libproc, -lproc) #include <libproc.h> taskid_t pr_settaskid
(struct ps_prochandle *P
, projid_t project
, int flags
() function injects the settaskid(2)
system call into the
target process P
by means of the agent LWP. If the process handle P
value NULL then this will be equivalent to calling settaskid(2)
currently running process.
The arguments project
have the same meaning as in settaskid(2)
for the full description and purpose of the settaskid
system call and its arguments.
() 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_settaskid
() function's return value is
that described in settaskid(2)
. Otherwise, -1
is returned and errno
to ENOSYS to indicate that the system call could not be injected.
For the full list of errors see the ERRORS
section in settaskid(2)
() 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
process handle P
does not support system call injection.
