How to get stored procedure parameters details?

Question

Where can I find information about stored procedure parameters? In my situation I need to know only the input parameters of given store procedure.

In the sys.o

Answer 1

It Contains a row for each parameter of an object that accepts parameters. If the object is a scalar function, there is also a single row describing the return value. That row will have a parameter_id value of 0.

SELECT *  
FROM sys.parameters  
WHERE object_id = object_id('SchemaName.ProcedureName')
