Manual Pages  — ACL_SET_TAG_TYPE

NAME

acl_set_tag_type – set the tag type of an ACL entry

CONTENTS

LIBRARY

Standard C Library (libc, -lc)

SYNOPSIS

#include <sys/types.h>
#include <sys/acl.h>

int
acl_set_tag_type(acl_entry_t entry_d, acl_tag_t tag_type);

DESCRIPTION

The acl_set_tag_type() function is a POSIX.1e call that sets the ACL tag type of ACL entry entry_d to the value of tag_type.

Valid values are:

ACL_USER_OBJ
Permissions apply to file owner

ACL_USER
Permissions apply to additional user specified by qualifier

ACL_GROUP_OBJ
Permissions apply to file group

ACL_GROUP
Permissions apply to additional group specified by qualifier

ACL_MASK
Permissions specify mask

ACL_OTHER
Permissions apply to other

ACL_OTHER_OBJ
Same as ACL_OTHER

ACL_EVERYONE
Permissions apply to everyone@

Calling acl_set_tag_type() with tag_type equal to ACL_MASK, ACL_OTHER or ACL_OTHER_OBJ brands the ACL as POSIX.1e. Calling it with ACL_EVERYONE brands the ACL as NFSv4.

RETURN VALUES

The acl_set_tag_type function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to indicate the error.

ERRORS

The acl_set_tag_type() function fails if:
[EINVAL]
  Argument entry_d is not a valid descriptor for an ACL entry. Argument tag_type is not a valid ACL tag type. ACL is already branded differently.
