ACL_CMP(3) Library Functions Manual ACL_CMP(3)
NAME
acl_cmp — compare two ACLs
LIBRARY
Linux Access Control Lists library (libacl, -lacl).
SYNOPSIS
<sys/types.h> <acl/libacl.h> int acl_cmp(acl_t acl1, acl_t acl2)
DESCRIPTION
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.
RETURN VALUE
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.
ERRORS
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.
STANDARDS
This is a non-portable, Linux specific extension to the ACL
manipulation functions defined in IEEE Std 1003.1e draft 17
(“POSIX.1e”, abandoned).
