| <h4 class="subsection">2.7.1 Reading symbols</h4> |
| <p>There are two stages to reading a symbol table from a BFD: |
| allocating storage, and the actual reading process. This is an |
| excerpt from an application which reads the symbol table: |
| </p> |
| <div class="example"> |
| <pre class="example"> long storage_needed; |
| asymbol **symbol_table; |
| long number_of_symbols; |
| long i; |
| |
| storage_needed = bfd_get_symtab_upper_bound (abfd); |
| |
| if (storage_needed < 0) |
| FAIL |
| |
| if (storage_needed == 0) |
| return; |
| |
| symbol_table = xmalloc (storage_needed); |
| ... |
| number_of_symbols = |
| bfd_canonicalize_symtab (abfd, symbol_table); |
| |
| if (number_of_symbols < 0) |
| FAIL |
| |
| for (i = 0; i < number_of_symbols; i++) |
| process_symbol (symbol_table[i]); |
| </pre></div> |
| |
| <p>All storage for the symbols themselves is in an objalloc |
| connected to the BFD; it is freed when the BFD is closed. |
