Understanding Source Code
The best way to understand what a hook does is to look at where it occurs in the source code.
- Action hooks look like this:
do_action( "hook_name" ) - Filter hooks look like this:
apply_filters( "hook_name", "what_to_filter" ).
Remember, this hook may occur in more than one file. Moreover, the hook's context may change from version to version.

| 236 | * value in the $userdata parameter array. |
| 237 | * |
| 238 | * If $userdata does not contain an 'ID' key, then a new user will be created |
| 239 | * and the new user's ID will be returned. |
