Section 125 CrPC vs Maintenance under Hindu Law

Yaar samajh nahi aaya, kuch confusion hai. Maine ek sawal dekha tha jo ek friend ne ask kiya tha. Sabne kaha ki 125 CrPC aur Hindu Law me maintenance ka concept hi alag alag hai. Lekin phir bhi, kuch jagah se dekha ki unmein similarities ho rahi hain.

125 CrPC kya chahta hai ki wife ko maintenance diya jaye, tabhi uske pas pataa chale ki uska husband aapne family ko support nahi kar raha. Lekin Hindu Law me kya, kya kuch alag nahi hai? Kya koi difference hai usmein isse 125 CrPC ke comparison me? Please help, kya samajhna hai, mere dimaag mein bhi confusion hai.
