ACL_SET_TAG_TYPE(3) FreeBSD Library Functions Manual ACL_SET_TAG_TYPE(3)

acl_set_tag_type
set the tag type of an ACL entry

Standard C Library (libc, -lc)

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

int
acl_set_tag_type(acl_entry_t entry_d, acl_tag_t tag_type);

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.

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.

The acl_set_tag_type() function fails if:
[]
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.

acl(3), acl_get_brand_np(3), acl_get_tag_type(3), posix1e(3)

POSIX.1e is described in IEEE POSIX.1e draft 17.

POSIX.1e support was introduced in FreeBSD 4.0. The acl_set_tag_type() function was added in FreeBSD 5.0.

The acl_set_tag_type() function was written by Chris D. Faulhaber <jedgar@fxp.org>.
June 25, 2009 FreeBSD 13.1-RELEASE
