PREfast detects a variety of precedence errors.
The following warnings are reported in this category:
| Warning number | Description |
|---|---|
| PREfast Warning 235 | (<non-zero constant> || <expression>) is always TRUE. |
| PREfast Warning 236 | (<expression> || <non-zero constant>) is always TRUE. |
| PREfast Warning 237 | (<zero> && <expression>) is always FALSE. |
| PREfast Warning 239 | (<non-zero constant> && <expression>) always evaluates to Boolean result of <expression>. |
| PREfast Warning 240 | (<expression> && <non-zero constant>) always evaluates to Boolean result of <expression>. |
| PREfast Warning 241 | Value returned from the finally block overrides the value returned from its corresponding try block. |
| PREfast Warning 242 | A jump out of this try block forces local unwind. |
| PREfast Warning 243 | Return from a finally block halts global unwind. |
| PREfast Warning 244 | Local declaration of <variable> hides global declaration. |
| PREfast Warning 245 | For-init declaration of <variable> hides global declaration. |
| PREfast Warning 246 | Local declaration of <variable> hides declaration of same name in outer scope. |
| PREfast Warning 247 | For-init declaration of <variable> hides declaration of same name in outer scope. |
| PREfast Warning 248 | DACL for a SECURITY_DESCRIPTOR structure set to NULL, resulting in an unprotected object. |
| PREfast Warning 249 | <kernel function> call without the MEM_RELEASE flag frees memory but not the address descriptors (VADs). |
| PREfast Warning 250 | <function> call without the MEM_RELEASE flag frees memory but not the address descriptors (VADs). |
| PREfast Warning 251 | InitializeCriticalSection indicates failure by raising an asynchronous exception. |
| PREfast Warning 252 | Untagged pool allocation. |
| PREfast Warning 253 | MmSecureVirtualMemory locks VADs not pages. |
| PREfast Warning 255 | _alloca indicates failure by raising a stack overflow exception. |
| PREfast Warning 257 | _alloca used in prohibited location. |
| PREfast Warning 258 | Using TerminateThread does not allow proper thread clean up. |
| PREfast Warning 259 | Labeled code is unreachable. |
| PREfast Warning 260 | Sizeof * Sizeof is almost always wrong. |
| PREfast Warning 261 | MustSucceed pool allocations are forbidden. |
| PREfast Warning 262 | Function uses <constant> bytes of stack. |
| PREfast Warning 263 | _alloca used in a loop. |
| PREfast Warning 281 | Incorrect order of operators. |
| PREfast Warning 282 | Incorrect operator. |
| PREfast Warning 285 | (<non-zero constant> || <non-zero constant>) is always TRUE. |
| PREfast Warning 286 | (<non-zero constant> || <expression>) is always TRUE. |
