Codex:

Updates user meta field based on user ID.

Use the $prev_value parameter to differentiate between meta fields with the same key and user ID. If the meta field for the user does not exist, it will be added. For historical reasons both the meta key and the meta value are expected to be "slashed" (slashes escaped) on input.
