pr_gettaskid —
inject gettaskid system call into victim process
Process Control Library (libproc, -lproc)
#include
<libproc.h>
taskid_t
pr_gettaskid(struct ps_prochandle
*P);
The
pr_gettaskid()
function injects the gettaskid(2)
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
gettaskid(2) on the currently
running process.
The
pr_gettaskid()
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_gettaskid() function's return value is that
described in gettaskid(2).
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 gettaskid(2).
The pr_gettaskid() function will fail
if:
ENOSYSSee LOCKING in libproc(3LIB).
