NO_EFFECT
EXP33-C. Do not read uninitialized memory
MSC12-C. Detect and remove code that has no effect
NULL_RETURNS
OPEN_ARGS
FIO03-C. Do not make assumptions about fopen() and file creation
OVERFLOW_BEFORE_WIDEN
INT18-C. Evaluate integer expressions in a larger size before comparing or assigning to that size

INT36-C. Converting a pointer to integer or integer to pointer
RACE_CONDITION
CON32-C. Prevent data races when accessing bit-fields from multiple threads
READLINK
POS30-C. Use the readlink() function properly
RESOURCE_LEAK
MEM00-C. Allocate and free memory in the same module, at the same level of abstraction
MEM31-C. Free dynamically allocated memory when no longer needed
RETURN_LOCAL
DCL30-C. Declare objects with appropriate storage durations
REVERSE_INULL
REVERSE_NEGATIVE
ARR32-C. Ensure size arguments for variable length arrays are in a valid range
SECURE_CODING
STR31-C. Guarantee that storage for strings has sufficient space for character data and the null terminator
SECURE_TEMP
FIO21-C. Do not create temporary files in shared directories
SIZECHECK
STACK_USE
MEM05-C. Avoid large stack allocations
STRING_NULL
STR32-C. Do not pass a non-null-terminated character sequence to a library function that expects a string
STRING_OVERFLOW
STRING_SIZE
TAINTED_STATIC
INT32-C. Ensure that operations on signed integers do not result in overflow
TAINTED_STRING
STR02-C. Sanitize data passed to complex subsystems
TAINTED_STRING_WARNING
FIO30-C. Exclude user input from format strings
TOCTOU
FIO01-C. Be careful using functions that use file names for identification
UNCAUGHT_EXCEPT
ERR30-C. Set errno to zero before calling a library function known to set errno, and check errno only after the function returns a value indicating failure
UNINIT
UNREACHABLE
UNUSED_VALUE
MSC13-C. Detect and remove unused values
USE_AFTER_FREE
MEM01-C. Store a new value in pointers immediately after free()
MEM30-C. Do not access freed memory
