- * True if  "l" bytes of "var" were captured.

- * The "snapend - (l) <= snapend" checks to make sure "l" isn't so large
- * that "snapend - (l)" underflows.
- *
- * The check is for <= rather than < because "l" might be 0.
- *
- * We cast the pointers to uintptr_t to make sure that the compiler
- * doesn't optimize away any of these tests (which it is allowed to
- * do, as adding an integer to, or subtracting an integer from, a
- * pointer assumes that the pointer is a pointer to an element of an
- * array and that the result of the addition or subtraction yields a
- * pointer to another member of the array, so that, for example, if
- * you subtract a positive integer from a pointer, the result is
- * guaranteed to be less than the original pointer value). See
