Visual C++ Compiler Warning C4114

Message Text

same type qualifier used more than once

Level

This is a level 1 warning.

Circumstances

Warning C4114 is concerned with modifiers in declarations. There are two cases.

First, repeating any of the following modifiers

• const
• __ptr32
• __ptr64
• volatile

causes warning C4114 if the Microsoft language extensions are enabled (as by /Ze, which is the default). Otherwise, such repetition is an error (C2289).

Second, and independently of /Za versus /Ze, warning C4114 follows from repeating signed or unsigned. In contrast, mixing signed and unsigned is always an error (C2042).
