NAME

dpns_getacl - get DPNS directory/file access control lists  

SYNOPSIS

#include <sys/types.h>
#include "dpns_api.h"

int dpns_getacl (const char *path, int nentries, struct dpns_acl *acl)  

DESCRIPTION

dpns_getacl gets the Access Control List associated with a DPNS directory/file.
path
specifies the logical pathname relative to the current DPNS directory or the full DPNS pathname.
nentries
specifies the number of entries that can fit in the buffer. If nentries is zero, the acl pointer can be NULL and the routine just returns the actual number of entries.
acl
is a pointer to an array of dpns_acl structures allocated by the application to receive the reply.

struct dpns_acl {
        unsigned char   a_type;
        int             a_id;
        unsigned char   a_perm;
};
a_type
is the ACL type: CNS_ACL_USER_OBJ, CNS_ACL_USER, CNS_ACL_GROUP_OBJ, CNS_ACL_GROUP, CNS_ACL_MASK or CNS_ACL_OTHER. Types for default entries are obtained by OR'ing the flag CNS_ACL_DEFAULT with one of the above types.
a_id
is the user or group numeric id.
a_perm
is the access permission in numeric form obtained by OR'ing some of the bits S_IROTH, S_IWOTH, S_IXOTH.
 

RETURN VALUE

This routine returns the actual number of entries if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.  

ERRORS

ENOENT
The named file/directory does not exist or is a null pathname.
EACCES
Search permission is denied on a component of the path prefix.
EFAULT
path is a NULL pointer or acl is a NULL pointer and nentries is greater than zero.
ENOTDIR
A component of path prefix is not a directory.
EINVAL
nentries is negative.
ENOSPC
nentries is less than the number of entries returned by the server.
ENAMETOOLONG
The length of path exceeds CA_MAXPATHLEN or the length of a path component exceeds CA_MAXNAMELEN.
SENOSHOST
Host unknown.
SENOSSERV
Service unknown.
SECOMERR
Communication error.
ENSNACT
Name server is not running or is being shutdown.
