Test Your Knowledge in Computers #268
Difficulty: Easy
In 1936, Turing published his paper 'On Computable Numbers, with an Application to the Entscheidungsproblem'. In this paper, Turing reformulated Kurt Godel's 1931 results on the limits of proof and computation, replacing Godel's universal arithmetic-based formal language with the formal and simple hypothetical devices that became known as Turing machines.

CR_SEEOTHERUIDS(9)					   BSD Kernel Developer's Manual					CR_SEEOTHERUIDS(9)

NAME
cr_seeotheruids -- determine visibility of objects given their user credentials SYNOPSIS
int cr_seeotheruids(struct ucred *u1, struct ucred *u2); DESCRIPTION
This function determines the visibility of objects in the kernel based on the real user IDs in the credentials u1 and u2 associated with them. The visibility of objects is influenced by the sysctl(8) variable security.bsd.see_other_uids. If this variable is non-zero then all objects in the kernel are visible to each other irrespective of their user IDs. If this variable is zero then the object with credentials u2 is vis- ible to the object with credentials u1 if either u1 is the super-user credential, or if u1 and u2 have the same real user ID. SYSCTL VARIABLES
security.bsd.see_other_uids Must be non-zero if objects with unprivileged credentials are to be able to see each other. RETURN VALUES
This function returns zero if the object with credential u1 can ``see'' the object with credential u2, or ESRCH otherwise. SEE ALSO
