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 -- 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:

The program above exits without freeing the memory.
In this case will the 1 gb of heap memory be returned... (9 Replies)
I see lot of ad-hoc shell scripts in our servers which don't have a shebang at the beginning .
Does this mean that it will run on any shell ?
