LFS_SEGWAIT(2)		       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  ac-
     quired for writing by any LFS filesystem.

     If  timeout  is non-zero, lfs_segwait() will return after timeout millisec-
     onds 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.
