—
inject meminfo system call into victim process

int
pr_meminfo
(struct ps_prochandle
*P, const uint64_t *addrs, int
addr_count, const uint_t *info,
int info_count, uint64_t
*outdata, uint_t *validity);
The
pr_meminfo
()
function injects the meminfo(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
meminfo(2) on the currently running
process.
The arguments addrs, addr_count, info, info_count, outdata, and validity have the same meaning as in meminfo(2). See meminfo(2) for the full description and purpose of the meminfo system call and its arguments.
The
pr_meminfo
()
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_meminfo
() function's return value is that
described in meminfo(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 meminfo(2).
The pr_meminfo
() function will fail
if:
ENOSYS
See LOCKING in libproc(3LIB).
