What platforms have something other than 8-bit char?
...
TI C62xx and C64xx DSPs also have 16-bit chars. (uint8_t isn't defined on that platform.)

Is “argv[0] = name-of-executable” an accepted standard or just a common convention?

_NSGetExecutablePath(NULL, &pathNameSize);
if (pathNameSize > pathNameCapacity)

How do I find the length of an array?
...td container or a C-style array. For example:
#include <iterator>
uint32_t data[] = {10, 20, 30, 40};

What is the argument for printf that formats a long?
... have used a macro instead to capture the semantic meaning of the type (eg uint64_t).
char c; // 8 bits
short s; // 16 bits
int i; // 32 bits (on modern platforms)
long l; // 32 bits
long long ll; // 64 bits
Back in the day, "int" was 16 bits. You'd think it would now be...
In-Place Radix Sort
...e.
So for sequences of length 3, one could create 64 buckets, maybe sized uint32, or uint64.
Initialize them to zero.
Iterate through your very very large list of 3 char sequences, and encode them as above.
Use this as a subscript, and increment that bucket.
Repeat this until all of your sequences ...
When is assembly faster than C?
... the high part of 64 bit integer multiplication: A portable version using uint64_t for 32x32 => 64-bit multiplies fails to optimize on a 64-bit CPU, so you need intrinsics or __int128 for efficient code on 64-bit systems.
