'identifier' : function must return a value
The function was declared as returning a value, but the function definition does not contain a return statement.
This error can be caused by an incorrect function prototype:
If the function does not return a value, declare the function with return type void.
Check that all possible branches of the function return a value of the type declared in the prototype.
C++ functions containing inline assembly routines that store the return value in the
AXregister may need a return statement. Copy the value inAXto a temporary variable and return that variable from the function.
The following sample generates C2561:
// C2561.cppintTest(int x) { if (x) { return; // C2561// try the following line instead// return 1; } return0; } intmain() { Test(1); }
