C - homebrew strtok

[M_D_K]

So this code came into existence cause avansc wanted to see how I'd do it and so he could use it. Clearly neither of us knew about strtok.

Code: Select all

char *nextToken(char* data, char delimiter)
{
    char *pos = strchr(data, (int)delimiter);
    if(pos == NULL)
    {
        return NULL;
    }

    char *ret = (char *)malloc((pos-data+1)*sizeof(char));
    strncpy(ret, data,(pos-data));
    
    //just in case read and write addresses overlap (it shouldn't)
    strcpy(data, pos+1);//here so strncpy doesn't fuck up

    return ret;
};

EDIT: So it turns out avansc likes this code more than strtok
EDIT2: Ginto made it segfault(no surprise there) so added a little something to remove user(coder) stupidity.

He mentioned that you had difficulty using it. Check the manual, it's sort of strange (NULL calls after first). The way it's handled also means you can't tokenize two strings in parallel with strtok.
