    Command:

    acl_size

    
    
    
    

    SYNOPSIS

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

    DESCRIPTION

         The acl_size() function return the size, in bytes, of the buffer required
         to hold the exportable, contiguous, persistent form of the ACL pointed to
         by the argument acl, when converted by acl_copy_ext().
    
         Any existing ACL entry descriptors that refer to entries in acl continue
         to refer to the same entries. Any existing ACL pointers that refer to the
         ACL referred to by acl continue to refer to the ACL. The order of ACL
         entries within acl remains unchanged.
    
    
    

    RETURN VALUE

         On success, the acl_size() function returns the size in bytes of the con-
         tiguous, persistent form of the ACL. On error, a value of (ssize_t)-1 is
         returned and errno is set appropriately.
    
    
    

    ERRORS

         If any of the following conditions occur, the acl_size() function returns
         a value of (ssize_t)-1 and sets errno to the corresponding value:
    
         [EINVAL]           The argument acl is not a valid pointer to an ACL.
