For ages, the function-linking feature of the src/*.c pages was broken and incomplete. Finally, all files from the src/ subdirectory have had their function definitions identified, and when you click on a function call, it *should* link you to the relevant function definition. If you see a function call not marked or a link not properly working (for example, sending you to the respective function in the 3.4.3 source), please make the relevant edit or hit me up, dizzylizzy in #nethackwiki on Freenode. It's been a long time coming and now it's all pretty. Props to DizzyBot for being a champ.
