## Detailed Description

Definitions for ACL mapping code.

This is what Apple says about ACL flags in sys/kauth.h:

<Apple> The low 16 bits of the flags field are reserved for filesystem internal use and must be preserved by all APIs. This includes round-tripping flags through user-space interfaces. The high 16 bits of the flags are used to store attributes and to request specific handling of the ACL. </Apple>

The constants are included for reference. We DONT expect them on the wire! We will ignore and spoil em.

## Function Documentation

## ◆ acltoownermode()

int acltoownermode | ( | const AFPObj * | obj,
|  | const struct vol * | vol,
|  | char * | path,
|  | struct stat * | st,
|  | struct maccess * | ma )
| extern

map ACL to user maccess

This is the magic function that makes ACLs usable by calculating the access granted by ACEs to the logged in user.

## ◆ afp_access()

int afp_access | ( | AFPObj * | obj,
|  | char * | ibuf,
|  | size_t | ibuflen,
|  | char * | rbuf,
|  | size_t * | rbuflen )

## ◆ afp_getacl()

int afp_getacl | ( | AFPObj * | obj,
|  | char * | ibuf,
|  | size_t | ibuflen,
|  | char * | rbuf,
|  | size_t * | rbuflen )

## ◆ afp_setacl()

int afp_setacl | ( | AFPObj * | obj,
|  | char * | ibuf,
|  | size_t | ibuflen,
|  | char * | rbuf,
|  | size_t * | rbuflen )
