[dtrace-discuss] a piece of dtrace source code

[陶捷 Tao Jie]

Dear all:

in file dt_proc.c

void
dt_proc_hash_create(dtrace_hdl_t *dtp)
{
 if ((dtp->dt_procs = dt_zalloc(dtp, sizeof (dt_proc_hash_t) +
     sizeof (dt_proc_t *) * _dtrace_pidbuckets *- 1*)) != NULL) {
......
......
......


Why does the size minus one? I have no idea about this :(



Regards
TJ
