Your code example actually answers this question:
static int
cursig(uintptr_t addr, uint_t flags, int argc, const mdb_arg_t *argv)
{
struct ps_prochandle *P;
const pstatus_t *psp;
if ((P = curproc()) == NULL)
return (DCMD_ERR);
if ((psp = Pstatus(P)) == NULL) {
mdb_warn("Pstatus failed");
return (DCMD_ERR);
}
(void) lwp_cursig(P, &psp->pr_lwp);
(void) Plwp_iter(P, (proc_lwp_f *)lwp_cursig, NULL);
return (DCMD_OK);
}
So, in general, I can I use any libproc functions from MDB proc target
modules?
