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.

I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:

Suppose I have a main() function with only one malloc statement allocating say some 1 gb memory. Also say my system has 1 gb of ram.
main()
{
malloc(1gb)
return(0)
}
The program above exits without freeing the memory.
In this case will the 1 gb of heap memory be returned... (9 Replies)

Hey All,
Quick question...
I'm writing a short script to check if a continuous port is running on a server.
I'm using "ps -ef | grep -v grep | grep processName" and I was wondering if it was better/more reliable to just check the
return code from the command or if its better to pipe to... (12 Replies)
I installed NetBSD 6.1.2 amd64 and can't find the apm utility. Is it not in the base system?
Is it necessary to recompile the default amd64 kernel to use apm?
Or is there a new method for power management and suspend/resume? (2 Replies)
Hi,
I am learning shell scripting for the first time. I use AT&T Korn Shell, Version AJM 93u+ 2012-08-01, compiled from source on NetBSD.
So far I have managed to set up what I think is a useful and pleasing shell prompt, which can be seen in the image attached to this post.
