ELF_GETIDENT(3) BSD Library Functions Manual ELF_GETIDENT(3)NAME
elf_getident -- return the initial bytes of a file
LIBRARY
ELF Access Library (libelf, -lelf)
SYNOPSIS
#include <libelf.h>
char *
elf_getident(Elf *elf, size_t *sz);
DESCRIPTION
Function elf_getident() returns a pointer to the initial bytes of the file for descriptor elf.
If argument sz is non-null, the size of the identification area returned is written to the location pointed to by sz. This location is set
to zero on errors.
RETURN VALUES
Function elf_getident() will return a non-NULL pointer to the initial bytes of the file if successful, or NULL if an error condition is
detected.
ERRORS
Function elf_getident() can fail with the following errors:
[ELF_E_ARGUMENT] A NULL value was passed in for argument elf.
[ELF_E_SEQUENCE] ELF descriptor elf was opened for writing and function elf_getident() was called before a call to elf_update(3).

ELF_GETSHDRNUM(3) BSD Library Functions Manual ELF_GETSHDRNUM(3)NAME
elf_getshdrnum -- return the number of sections in an ELF file
LIBRARY
ELF Access Library (libelf, -lelf)
SYNOPSIS
#include <libelf.h>
int
elf_getshdrnum(Elf *elf, size_t *shnum);
DESCRIPTION
Function elf_getshdrnum() retrieves the number of ELF sections associated with descriptor elf and stores it into the location pointed to by
argument shnum.
This routine allows applications to uniformly process both normal ELF objects, and ELF objects that use extended section numbering.
RETURN VALUES
Function elf_getshdrnum() returns zero value if successful, or -1 in case of an error.
ERRORS
Function elf_getshdrnum() can fail with the following errors:
[ELF_E_ARGUMENT] A NULL value was passed in for argument elf.
[ELF_E_ARGUMENT] Argument elf was not for an ELF file.
[ELF_E_ARGUMENT] Argument elf lacks an ELF Executable header.

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:
$ ls -ld /usr/bin /usr/bin/cat

and would like to sort it numerically on the first field. I tried:
sort -nr --key=1 ....
The output I get is:

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.

Usually when I on the evening go to bed I take some interesting book with me. I read it for a while to get me down to sleep. Probably most people seek information from the Nett by googleing but I am so oldfashioned I prefer a real book ;)
