acltotext(3SEC) 				       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 <sys/acl.h>

       char *acltotext(aclent_t *aclbufp, int aclcnt);

       aclent_t *aclfromtext(char *acltextp, int *aclcnt);

DESCRIPTION

       The  acltotext()  function converts an internal ACL representation pointed to by aclbufp into an external ACL representation. 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 argu-
       ment indicates the number of ACL entries found.

       An external ACL representation is defined as follows:

	      <acl_entry>[,<acl_entry>]...

       Each <acl_entry> 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.
		       Otherwise, 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 discretionary 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 NULL.

       Upon successful completion, the aclfromtext() function returns a pointer to a list of ACL entries. Otherwise, it returns NULL.
