Code error types detected by purify

I. red exclamation mark 1. ABR: Array bounds read Array out-of-bounds read (only the array allocated by dynamic memory is detected, and the global, local, and static arrays cannot be detected ). 2. ABW: Array Bounds Write Array out-of-bounds write (only the array allocated by dynamic memory is detected, and the global, local, and static arrays cannot be checked 3. abwl: Late detect Array Bounds Write (an abwl message Indicates that the program wrote a value before the beginning or after The end of an allocated block of memory) 4. BSR: Beyond stack read The function may have read a pointer outside the current stack. For example, if the program encounters an exception when writing the variable value, a BSR error occurs when reading the variable. (Not applicable to local arrays in the stack) 5. bsw: Beyond stack write The function may write a pointer out of the current stack. (Not applicable to local arrays in the stack) 6. Exu: unhandled exception Unprocessed exceptions 7. FFM: freeing freed memory Releasing released memory. 8. FIM: freeing Invalid Memory Try to release unallocated and invalid memory. 9. FMM: freeing mismatched memory Release mismatched memory and use incorrect API functions to release some memory types. 10. FMR: free memory read Read the released or unallocated memory. 11. fmw: free memory write Write the released or unallocated memory. 12. FMWL: Late detect free memory write 13. IPR: Invalid Pointer read The program is reading an invalid memory region and cannot set the address. 14. IPW: Invalid Pointer write The program is writing an Invalid Address in the memory area. Red Zone For Error Detection runs, the bytes that are placed at the beginning And end of each allocated block of memory in a program at run time. Red Zone is used to detect Array bounds read (ABR), Array Bounds Write (ABW), and late detect Array Bounds Write (abwl) errors. 15. NPR: NULL pointer read Null Pointer read. 16. npw: NULL pointer write Null Pointer write. 2. Yellow Warning Information 1. com: com api/interface failure Com operation failed. In every com After an API or COM interface is called, purify checks the hresult. If the value is not s_ OK indicating that the operation is successful, this error is displayed. 2. HAN: Invalid handle Invalid handle. A non-handle value or an error type handle appears in the expected handle. 3. ilk: COM interface leak COM interface vulnerability. This prompt is displayed when the total number of references to a COM interface is greater than 1. 4. MLK: Memory Leak Heap Memory leakage. The memory block does not contain any content or is not referenced by any pointer. The error message is displayed in either of the following cases. A. The local memory is allocated to the function, but it is not free when you exit the function. B. the pointer of the memory block is cleared or changed or not in its scope. If the section of the program where the memory is allocated and Leaked is executed repeatedly, you might eventually run out of swap Space, causing slow downs and crashes. This is a serous problem Long-running, interactive programs. 5. Par: Bad Parameter The program passes an incorrect parameter when calling a common function during WIN32API or C running. 6. UMC: uninitialized memory copy Copy an uninitialized value from one memory area to another. 7. UMR: uninitialized memory read Read the value of the uninitialized memory block. 3. Blue prompt information 1. Box: MessageBox If the MessageBox () or messageboxex () functions are used in the program, the message is displayed after the purify operation is completed. 2. exc: Continued exception 3. exh: handled exception 4. Exi: ignored exception 5. Hiu: handle in use After the handle is assigned, it is not released. 6. MAF: Memory Allocation failure Memory Allocation failed. 7. Miu: Memory in use The heap memory to be allocated already has a pointer. 8. mpk: Potential Memory Leak Heap memory may be leaked. There is no pointer at the beginning of the memory block, but the pointer inside the block seems to point. 9. ODS: outputdebugstring The program calls the outputdebugstring function.
