ACL_SET_TAG_TYPE(3)

NAME
acl_set_tag_type - set the tag type of an ACL entry

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
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

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.
