ACL_SET_TAG_TYPE(3)        Library Functions Manual        ACL_SET_TAG_TYPE(3)

NAME
     acl_set_tag_type - set the tag type of an ACL entry

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.
