What does "sts" stand for?

[Paul Colby <paul@xxxxxxxxxxx>]

Hi guys,

I'm just curious... in various places, such as the pmdaCache man page,
and the Simple PMDA example, PCP API return values are assigned to
variables called "sts".  I understand that this, usually at least, an
integer such that negative values indicate errors, etc, but I'm just
curious as to the choice of the three letters "sts".  Do they stand
for something in particular?

Cheers,

pc
