<h4 class="subsection">2.7.3 Mini Symbols</h4>
|
|
|
|
<p>Mini symbols provide read-only access to the symbol table.
|
|
They use less memory space, but require more time to access.
|
|
They can be useful for tools like nm or objdump, which may
|
|
have to handle symbol tables of extremely large executables.
|
|
|
|
<p>The <code>bfd_read_minisymbols</code> function will read the symbols
|
|
into memory in an internal form. It will return a <code>void *</code>
|
|
pointer to a block of memory, a symbol count, and the size of
|
|
each symbol. The pointer is allocated using <code>malloc</code>, and
|
|
should be freed by the caller when it is no longer needed.
|
|
|
|
<p>The function <code>bfd_minisymbol_to_symbol</code> will take a pointer
|
|
to a minisymbol, and a pointer to a structure returned by
|
|
<code>bfd_make_empty_symbol</code>, and return a <code>asymbol</code> structure.
|
|
The return value may or may not be the same as the value from
|
|
<code>bfd_make_empty_symbol</code> which was passed in.
