NAME
dolock —
lock port for concurrent
builds
SYNOPSIS
dolock |
lockname |
DESCRIPTION
dolock creates a lock named
lockname using
open(2). If the lock is already held, it will display one single wait
message on stderr, sleep and retry until satisfaction.
This implements a locking mechanism for ports building, see ‘LOCK INFRASTRUCTURE’ in ports(7) for details. See also dbp(1) for a complementary lock infrastructure when using dpb.
