acl_size(3)acl_size(3)NAMEacl_size - Determines the size of the contiguous, persistent represen‐
tation of the given ACL
SYNOPSIS
#include <sys/acl.h>
ssize_t acl_size(
acl_t acl_d );
LIBRARY
Security Library (libpacl.a)
PARAMETERS
The working storage internal representation of an ACL that the contigu‐
ous, persistent representation size is desired on.
DESCRIPTION
NOTE: This function is based on Draft 13 of the POSIX P1003.6 stan‐
dard.
Given an ACL, the acl_size() function determines the number of bytes
required for storing the ACL if converted to contiguous, persistent
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:
The acl_d argument does not point to an ACL structure.
