copy an ACL entry

Linux Access Control Lists library (libacl, -lacl).

#include <sys/types.h>
#include <sys/acl.h>

acl_copy_entry(acl_entry_t dest_d, acl_entry_t src_d);

The acl_copy_entry() function copies the contents of the ACL entry indicated by the src_d descriptor to the existing ACL entry indicated by the dest_d descriptor. The src_d and dest_d descriptors may refer to entries in different ACLs.

The acl_copy_entry() function returns the value 0 if successful; 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_copy_entry() function returns -1 and sets errno to the corresponding value:
The argument src_d or dest_d is not a valid descriptor for an ACL entry.

The arguments src_d and dest_d reference the same ACL entry.
