Hydroxy nitriles help

How are they made and what happens if you add HCl to them?It would be appreciated if you added equations.
2-hydroxynitriles are made by nucleophilic addition of HCN to a carbonyl compound.
RCOR + HCN -> RC(OH)(CN)R
They are hydrolysed to 2-hydroxycarboxylic acids in the presence of HCl.
RC(OH)(CN)R + 2H2O + HCl -> RC(OH)(COOH)R + NH4Cl

If I have CH3CHOHCN+HCl-->What do I get? where would I get an oxygen to make a hydroxy carboxylic acid?

when you hydrolyse CH3CH(OH)CN with HCl, you get CH3CH(OH)COOH and NH4Cl
From water

Why is water not included in the equation?

Ok thank you so it is a 2 step equation.

RC(OH)(CN)R + 2H2O + HCl -> RC(OH)(COOH)R + NH4Cl

first the nitrile is hydrolysed to an amide RC(OH)(CONH2)R
then the amide is hydrolysed to the carboxylic acid RC(OH)(COOH)R
