LIBRARY
library “libc”
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
Theacl_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.
