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 file system specified by
*fsidp or if
*fsidp is -1, until a segment is acquired for writing by
any LFS file system.
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.

lfs_segwait() indicates:
-

-
- [

- A signal was delivered before the time limit expired and
