This goes against Theodore Ts'o preference, but seems to reflect the consensus from the largery community. I weakened the protection against accidental interposition somewhat. Since the declaration is a new header file, I do not use a function-like macro to prevent a definition of a function named “getrandom”, and non-GNU compilers do not get any redirection. The rationale is that if you interpose the function after including , you probably know what you are doing. The redirect to __libc_getrandom still provides interposition protection if other translation units define a getrandom function without knowledge of .
