+This query highlights calls to the standard library functions <code>abort, exit, getenv</code> and <code>system</code>.
 The functions <code>abort</code> and <code>exit</code> should not be called as they immediately terminate the program
 and will bypass all the normal error and exception handling routines in the software. This is especially important in
 software which is run on systems without an interactive OS, as restarting the software may require a complete reboot

+This query highlights return statements that return pointers to an object allocated on the stack. The lifetime
 of a stack allocated memory location only lasts until the function returns, , and 
 the contents of that memory become undefined after that. Clearly, using a pointer to stack 
 memory after the function has already returned will have undefined results.

 machine. Manually manipulating the bits in the float is prone to mistakes and is unportable. Floating point
 implementations can vary across architectures, and bit-field packing can differ across compilers,
 making manual bit-manipulation of floats inadvisable.

 should not be changed, since they are usually stored in the data section, and depending on the architecture,

+This query finds unsigned values that are being negated. Behavior is undefined in such cases.
 Negating integer values produces the two's complement of that number, which cannot represent negative
 values of large unsigned values (values where the sign bit is used) and are most likely to be interpreted 
 as a smaller positive integer instead.
