Drupal's APIs
If you are interested in developing Drupal modules or hacking away at the Drupal core then this is the place to find details about all the functions and classes defined in Drupal.
Drupal uses Doxygen to automatically generate documentation from the latest Drupal sources. This allows us to ensure that documentation is up-to-date, and to simultaneously track multiple versions of the documentation.
API Documentation is available from api.drupal.org for:
- Drupal CVS HEAD - the latest, bleeding edge sources. More info...
- Drupal 6.x
- Drupal 5.x
- Drupal 4.7.x
- Drupal 4.6.x
For guidelines on how to document code with Doxygen, see Doxygen formatting conventions. Example modules can be found in the contributions/docs directory in CVS. See Your own api.drupal.org site for information on how to set it up.
