Compiler Error C2191

second parameter list longer than first

Remarks

A C function was declared a second time with a longer parameter list. C does not support overloaded functions. Without /Za, the compiler emits Compiler Warning (level 1) C4031 instead.

Example

The following example generates C2191:

// C2191.c
// compile with: /Za /c

void func1(int);
void func1(int, float);   // C2191, longer parameter list

void func2(int, float);   // OK
