acl_is_trivial_np3
Determine whether acl is trivial
Usage
#include <sys/types.h>
#include <sys/acl.h>
int
acl_is_trivial_np(const acl_t aclp, int *trivialp);
Library
Standard C Library (libc, -lc)
Overview
The acl_is_trivial_np() function determines whether the ACL pointed to by the argument acl is trivial. Upon successful completion, the location referred to by the argument trivialp will be set to 1, if the ACL aclp points to is trivial, or 0 if it's not.
ACL is trivial if it can be fully expressed as a file mode without losing any access rules. For POSIX.1e ACLs, ACL is trivial if it has the three required entries, one for owner, one for owning group, and one for other. For NFSv4 ACLs, ACL is trivial if it is identical to the ACL generated by acl_strip_np(3). Files that have non-trivial ACL have a plus sign appended after mode bits in "ls -l" output.
Return values
The acl_is_trivial_np() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to indicate the error.
