<b>Checking Return Values</b>.
Callers of internal OS functions should always check return values for an error.
At a minimum, a debug statement should indicate that an error has occurred.
The calling logic intentionally ignores the returned value, then the function return value should be explicitly cast to <code>(void)</code> to indicate that the return value is intentionally ignored.
An exception of for standard functions for which people have historically ignored the returned values, such as <code>printf()</code> or <code>close</code>.
All calls to <code>malloc</code> or <code>realloc</code> must be checked for failures to allocate memory.
Ignored return values are always suspicious.
All calls to <code>malloc</code> or <code>realloc</code>, in particular, must be checked for failures to allocate memory to avoid use of NULL pointers.
