LFS_SEGWAIT(2) BSD System Calls Manual LFS_SEGWAIT(2)
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 or not.
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 space.
[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.
lfs_bmapv(2), lfs_markv(2), lfs_segclean(2), lfs_cleanerd(8)
The lfs_segwait() function call appeared in 4.4BSD.
