File Access Control Library Functions acltotext(3SEC)
NAME
acltotext, aclfromtext - convert internal representation to
or from external representation
SYNOPSIS
cc [ flag... ] file... -lsec [ library... ]
#include
char *acltotext(aclentt *aclbufp, int aclcnt);
aclentt *aclfromtext(char *acltextp, int *aclcnt);
DESCRIPTION
The acltotext() function converts an internal ACL represen-
tation pointed to by aclbufp into an external ACL represen-
tation. The space for the external text string is obtained
using malloc(3C). The caller is responsible for freeing the
space upon completion..
The aclfromtext() function converts an external ACL
representation pointed to by acltextp into an internal ACL
representation. The space for the list of ACL entries is
obtained using malloc(3C). The caller is responsible for
freeing the space upon completion. The aclcnt argument indi-
cates the number of ACL entries found.
An external ACL representation is defined as follows:
[,]...
Each contains one ACL entry. The external
representation of an ACL entry contains two or three colon-
separated fields. The first field contains the ACL entry tag
type. The entry type keywords are defined as:
user This ACL entry with no UID specified in the
ACL entry ID field specifies the access
granted to the owner of the object. Other-
wise, this ACL entry specifies the access
granted to a specific user-name or user-id
number.
group This ACL entry with no GID specified in the
ACL entry ID field specifies the access
granted to the owning group of the object.

Otherwise, this ACL entry specifies the
access granted to a specific group-name or
group-id number.
other This ACL entry specifies the access granted
to any user or group that does not match
any other ACL entry.
mask This ACL entry specifies the maximum access
granted to user or group entries.
default:user This ACL entry with no uid specified in the
ACL entry ID field specifies the default
access granted to the owner of the object.
Otherwise, this ACL entry specifies the
default access granted to a specific user-
name or user-ID number.
default:group This ACL entry with no gid specified in the
ACL entry ID field specifies the default
access granted to the owning group of the
object. Otherwise, this ACL entry specifies
the default access granted to a specific
group-name or group-ID number.
default:other This ACL entry specifies the default access
for other entry.
default:mask This ACL entry specifies the default access
for mask entry.
The second field contains the ACL entry ID, as follows:
uid This field specifies a user-name, or user-ID if
there is no user-name associated with the user-ID
number.
gid This field specifies a group-name, or group-ID if
there is no group-name associated with the group-ID
number.

empty This field is used by the user and group ACL entry
types.
The third field contains the following symbolic discretion-
ary access permissions:
r read permission
w write permission
x execute/search permission
- no access
RETURN VALUES
Upon successful completion, the acltotext() function returns
a pointer to a text string. Otherwise, it returns NUL.
Upon successful completion, the aclfromtext() function
returns a pointer to a list of ACL entries. Otherwise, it
returns NUL.
