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.

NAME
aclsort - sort an ACL SYNOPSIS
cc [ flag ... ] file ... -lsec [ library ... ] #include <sys/acl.h> int aclsort(int nentries, int calclass, aclent_t *aclbufp); DESCRIPTION
The aclbufp argument points to a buffer containing ACL entries. The nentries argument specifies the number of ACL entries in the buffer. The calclass argument, if non-zero, indicates that the CLASS_OBJ (ACL mask) permissions should be recalculated. The union of the permission bits associated with all ACL entries in the buffer other than CLASS_OBJ, OTHER_OBJ, and USER_OBJ is calculated. The result is copied to the permission bits associated with the CLASS_OBJ entry. The aclsort() function sorts the contents of the ACL buffer as follows: o Entries will be in the order USER_OBJ, USER, GROUP_OBJ, GROUP, CLASS_OBJ (ACL mask), OTHER_OBJ, DEF_USER_OBJ, DEF_USER, DEF_GROUP_OBJ, DEF_GROUP, DEF_CLASS_OBJ (default ACL mask), and DEF_OTHER_OBJ. o Entries of type USER, GROUP, DEF_USER, and DEF_GROUP will be sorted in increasing order by ID. The aclsort() function will succeed if all of the following are true: o There is exactly one entry each of type USER_OBJ, GROUP_OBJ, CLASS_OBJ (ACL mask), and OTHER_OBJ. o There is exactly one entry each of type DEF_USER_OBJ, DEF_GROUP_OBJ, DEF_CLASS_OBJ (default ACL mask), and DEF_OTHER_OBJ if there are any default entries. o Entries of type USER, GROUP, DEF_USER, or DEF_GROUP may not contain duplicate entries. A duplicate entry is one of the same type con- taining the same numeric ID. RETURN VALUES
Upon successful completion, the function returns 0. Otherwise, it returns -1. ATTRIBUTES
