.SH "DESCRIPTION"
.PP
Call this to establish a lease on the file\&. The
\(lqlease\(rq
argument is not used for F_UNLCK requests and may be NULL\&. For commands that set or alter an existing lease, the (*lease)\->fl_lmops\->lm_break operation must be set; if not, this function will return \-ENOLCK (and generate a scary\-looking stack trace)\&.
.PP
The
\(lqpriv\(rq
pointer is passed directly to the lm_setup function as\-is\&. It may be NULL if the lm_setup operation doesn\*(Aqt require it\&.
