DPNS_GETACL(3)
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 path
- name.
- 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 nen
- tries 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.
