◆ castArgToParamTypeIfNeeded()

static SVal castArgToParamTypeIfNeeded ( const CallEvent Call,
unsigned  ArgIdx,
SVal  ArgVal,
SValBuilder SVB 
)
static

Cast the argument value to the type of the parameter at the function declaration.

Returns the argument value if it didn't need a cast. Or returns the cast argument if it needed a cast. Or returns 'Unknown' if it would need a cast but the callsite and the runtime definition don't match in terms of argument and parameter count.
