* snprintf() on MSVCRT returns -1 (instead of required buffer length) |
|
* if the input buffer isn't big enough. Also, if the required buffer |
|
* length is exactly identical to the input buffer size, or if the |
|
* return value is -1 because the input buffer isn't big enough, MSVCRT |
|
* will fail to NULL-terminate the output buffer. vsnprintf() has the |
|
* same issue. |
|
* |
|
* Thus, provide our own fallback wrappers with correct behaviour. |
