lfs_segwait - wait until a segment is written
Standard C Library (libc, -lc)
lfs_segwait(fsid_t *fsidp, struct timeval *tv);
lfs_segwait() blocks until a new segment is acquired for writing by the
filesystem specified by *fsidp or if *fsidp is -1, until a segment is
acquired for writing by any LFS filesystem.
If timeout is non-zero, lfs_segwait() will return after timeout milliseconds
regardless of whether a new segment has been designated for writing
lfs_segwait() returns 0 if a new segment was acquired; 1 if it timed out;
or -1 on error.
An error return from lfs_segwait() indicates:
[EFAULT] fsidp points outside the process's allocated address
[EINTR] A signal was delivered before the time limit expired
and before a new segment was designated for writing.
[EINVAL] The specified time limit is negative.

The lfs_segwait() function call appeared in 4.4BSD.
