94 /* Some systems fail to define SIZE_MAX in <stdint.h>, even though C99 requires it...
95 * Conversion from signed to unsigned is defined in 6.3.1.3 (Signed and unsigned integers) p2,
96 * which says: "the value is converted by repeatedly adding or subtracting one more than the
97 * maximum value that can be represented in the new type until the value is in the range of the
99 * So -1 gets converted to size_t by adding SIZE_MAX + 1, which results in SIZE_MAX.
101 # define SIZE_MAX ((size_t)-1)
106 * UINT16_MAX does not appear to be defined on Arduino so we define it here.
