| 56 | 8.5.1 Dl Objects | |
| 57 | </H2> | |
| 58 | ||
| 59 | <P> | |
| 60 | Dl objects, as returned by <tt class="function">open()</tt> above, have the | |
| 61 | following methods: | |
| 62 | ||
| 63 | <P> | |
| 64 | <dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline"> | |
| 65 | <td><nobr><b><tt id='l2h-2992' xml:id='l2h-2992' class="method">close</tt></b>(</nobr></td> | |
| 66 | <td><var></var>)</td></tr></table></dt> | |
| 67 | <dd> | |
| 68 | Free all resources, except the memory. | |
| 69 | </dl> | |
| 70 | ||
| 71 | <P> | |
| 72 | <dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline"> | |
| 73 | <td><nobr><b><tt id='l2h-2993' xml:id='l2h-2993' class="method">sym</tt></b>(</nobr></td> | |
| 74 | <td><var>name</var>)</td></tr></table></dt> | |
| 75 | <dd> | |
| 76 | Return the pointer for the function named <var>name</var>, as a number, if | |
| 77 | it exists in the referenced shared object, otherwise <code>None</code>. This | |
| 78 | is useful in code like: | |
| 79 | ||
| 80 | <P> | |
| 81 | <div class="verbatim"><pre> | |
| 82 | >>> if a.sym('time'): | |
| 83 | ... a.call('time') | |
| 84 | ... else: | |
| 85 | ... time.time() | |
| 86 | </pre></div> | |
| 87 | ||
| 88 | <P> | |
| 89 | (Note that this function will return a non-zero number, as zero is the | |
| 90 | <tt class="constant">NULL</tt> pointer) | |
| 91 | </dl> | |
| 92 | ||
| 93 | <P> | |
| 94 | <dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline"> | |
| 95 | <td><nobr><b><tt id='l2h-2994' xml:id='l2h-2994' class="method">call</tt></b>(</nobr></td> | |
| 96 | <td><var>name</var><big>[</big><var>, arg1</var><big>[</big><var>, arg2...</var><big>]</big><var></var><big>]</big><var></var>)</td></tr></table></dt> | |
| 97 | <dd> | |
| 98 | Call the function named <var>name</var> in the referenced shared object. | |
| 99 | The arguments must be either Python integers, which will be | |
| 100 | passed as is, Python strings, to which a pointer will be passed, | |
| 101 | or <code>None</code>, which will be passed as <tt class="constant">NULL</tt>. Note that | |
| 102 | strings should only be passed to functions as <tt class="ctype">const char*</tt>, as | |
| 103 | Python will not like its string mutated. | |
| 104 | ||
| 105 | <P> | |
| 106 | There must be at most 10 arguments, and arguments not given will be | |
| 107 | treated as <code>None</code>. The function's return value must be a C | |
| 108 | <tt class="ctype">long</tt>, which is a Python integer. | |
