ACL_SET_TAG_TYPE(3) Library Functions Manual ACL_SET_TAG_TYPE(3)

set the tag type of an ACL entry

Linux Access Control Lists library (libacl, -lacl).

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

acl_set_tag_type(acl_entry_t entry_d, acl_tag_t tag_type);

The acl_set_tag_type() function sets the tag type of the ACL entry indicated by the argument entry_d to the value of the argument tag_type.

Any ACL entry descriptors that refer to the entry referred to by entry_d continue to refer to that entry.

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.

If any of the following conditions occur, the acl_set_tag_type() function returns -1 and sets errno to the corresponding value:
The argument entry_d is not a valid descriptor for an ACL entry.

The argument tag_type is not a valid tag type.
