NetBSD 6.1.5 - man page for lfs_segwait (netbsd section 2)

LFS_SEGWAIT(2)			     BSD System Calls Manual			   LFS_SEGWAIT(2)

NAME
     lfs_segwait -- wait until a segment is written

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <sys/types.h>

     int
     lfs_segwait(fsid_t *fsidp, struct timeval *tv);

DESCRIPTION
     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.

RETURN VALUES
     lfs_segwait() returns 0 if a new segment was acquired; 1 if it timed out; or -1 on error.

ERRORS
     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.

SEE ALSO
     lfs_bmapv(2), lfs_markv(2), lfs_segclean(2), lfs_cleanerd(8)

HISTORY
     The lfs_segwait() function call appeared in 4.4BSD.
