What is "vinitaruci"

Vinītaruci (?-594) was an Indian Buddhist monk who in 580 came to support preaching of Buddhism in Vietnam, being notable as one of the first direct influences on Vietnam in the History of Buddhism in India and in the development of Vietnamese Thiền or Chinese Chán Zen Buddhism in Vietnam. He is known in Vietnam as Tì-ni-đa-lưu-chi (from the Sino-Vietnamese transcription of the Sanskrit 毘尼多流支) and also by the Chinese Sino-Vietnamese name Diệt Hỉ in Chinese-language texts of Vietnamese Buddhism. He was from Oḍḍiyāna, traditionally identified as a place in the Swat valley.
