I'm not aware of a list that specifically names all such functions, but 
the library docs says that for each function individually.  If you look 
up each function in the docs before committing to an algorithm, you are 
safe.

Search libc.info for "to assist" and "always returns", and you will find 
the handful of functions involved.

These issues shouldn't be in the FAQ, that's what library docs is for.
