Question

I’m reading from a file and need to split a string by null char.

    *Buff = "ABC \0 NAME \0 1231 \0 12.32";
    Tok = strtok(Buff,'\0');
    printf("Tok %s \n", Tok);

This does not work, strtok can not take a null argument.

Answer 1

Just use strlen(the_string) + 1 to get the tokens:

Example:

Tok = Buff;
Tok += strlen(Tok) + 1;    // first token
Tok += strlen(Tok) + 1;    // second token
Tok += strlen(Tok) + 1;    // third token, etc.

The terminating condition is when Tok >= Buff + sizeof "ABC \0 NAME \0 1231 \0 12.32".
