> ELF binary files consist of several sections. Each section has it's own
|
|
responsibility: some contain executable code; others describe program dependencies;
|
|
others symbol tables and so on. See the TIS documentation for a full description of each section.

<P

> To see how many sections the ELF file contains, including their
|
|
names and sizes, is demonstated in the following code:
|

<PRE
|
|
CLASS="PROGRAMLISTING"
|
|
> int nSecNo = pReader->GetSectionsNum();
|
|
for ( int i = 0; i < nSecNo; ++i ) { // For all sections
|

const IELFISection* pSec = pReader->GetSection( i );

std::cout << pSec->GetName() << '' ''
|

<< pSec->GetSize() << std::endl;

pSec->Release();

> First, the number of sections are received; next, a pointer
|
|
on the <FONT
|
|
COLOR="RED"
|
|
>IELFISection</FONT
|
|
> interface. Using this interface,
|
|
access is gained to the different section attributes: size, type, flags and address.
|
|
To get a buffer that contains the section's bytes use the
|
|
<TT
|
|
CLASS="METHODNAME"
|
|
>GetData()</TT
|
|
> member function of this interface.
|
|
See the <FONT

|
