owed child support...jail?

[Layla]

my daughters father has not paid any child support,he has a job, since it was ordered which was in january. He has a court date in a month. my question is what will happen if he doesnt show up to his hearing? if he gets arrested and put in jail will he have to pay his owed child support before getting out? And is it abandonment since he hasnt payed anything in 6 months? i live in nc..please help me with whatever u can thnx
