.SH "DESCRIPTION"
.PP
Allocate new ID above or equal to
\fIstart\fR\&. It should be called with any required locks to ensure that concurrent calls to
\fBida_get_new_above\fR
/
\fBida_get_new\fR
/
\fBida_remove\fR
are not allowed\&. Consider using
\fBida_simple_get\fR
if you do not have complex locking requirements\&.
.PP
If memory is required, it will return
\fB\-EAGAIN\fR, you should unlock and go back to the
\fBida_pre_get\fR
call\&. If the ida is full, it will return
\fB\-ENOSPC\fR\&. On success, it will return 0\&.
.PP
\fIid\fR
returns a value in the range
\fIstart\fR
\&.\&.\&.
\fB0x7fffffff\fR\&.
