#include <sys/acl.h> ssize_t acl_size(
acl_t acl_d);

Given an ACL, the acl_size() function determines the number of bytes required for storing the ACL if converted to data package internal representation using acl_copy_ext().

RETURN VALUES

Upon successful completion, the acl_size function returns the size of the ACL.  Otherwise, a value of -1 is returned and errno is set to indicate the error. 

ERRORS

If any of the following conditions occur, the acl_size() function sets errno to the corresponding value:

[EINVAL]The acl_d argument does not point to an ACL structure.
