Or a pointer inside that string.


To tokenize

char input[16] = "abc,d,efg";

at ',' boundaries, you'd first do

char const *firstToken(strtok(input,","));

and then, until strok() returns 0,

char const *subsequentToken(strtok(0,","));

, i.e. if the first argument is 0, strtok() is to continue the previous
tokenization. For this to work, strok() needs some internal memory.
