 # Compiler Error C3187
 
-> '`__func__`' : is only available within the body of a function
+> '`__func__`': is only available within the body of a function
+
+## Remarks
+
+The predefined identifier [`__func__`](../../cpp/func.md) is not available outside the body of a function.
+
+To correct this error, move the identifier inside the body of a function.
+
+## Example
+
+The following example generates C3187:
+
+```cpp
+// C3187.cpp
+// compile with: /c
+
+auto global = __func__;   // C3187, usage in global scope
+
+void func(const char* f = __func__);   // C3187, usage in parameter list
+```
 
-The predefined macro is not available outside the body of a function.
+## See also
 
-To correct this error, move the macro inside the body of a function.
