ACL_CMP(3) BSD Library Functions Manual ACL_CMP(3)
acl_cmp — compare two ACLs
Linux Access Control Lists library (libacl, -lacl).
#include <sys/types.h>
#include <acl/libacl.h>
int
acl_cmp(acl_t acl1, acl_t acl2);
The acl_cmp() function compares the ACLs pointed to by the arguments
acl1 and acl2 for equality. The two ACLs are considered equal if for
each entry in acl1 there is an entry in acl2 with matching tag type,
qualifier, and permissions, and vice versa.
If successful, the acl_cmp() function returns 0 if the two ACLs acl1
and acl2 are equal, and 1 if they differ. Otherwise, the value -1 is
returned and the global variable errno is set to indicate the error.
If any of the following conditions occur, the acl_cmp() function
returns -1 and sets errno to the corresponding value:
[EINVAL] The argument acl1 is not a valid pointer to an ACL.
The argument acl2 is not a valid pointer to an ACL.
This is a non-portable, Linux specific extension to the ACL
manipulation functions defined in IEEE Std 1003.1e draft 17
(“POSIX.1e”, abandoned).
