小计~strtok_r来取list

static unsigned int split(const char *str, const char *deli, AVL_DLIST_T *list)
{
int i = 0;
char *buf = NULL;


if (str == NULL)
{
return -1;
}

buf = (char *)malloc(strlen(str) + 1);
strcpy(buf, str);
char *gg;


char *p = strtok_r(buf, deli, &gg);

char *split_str;


while (p != NULL)
{
split_str = (char*)malloc(strlen(p) + 1);
  strcpy(split_str, p);
dlist_append(list, (void*)split_str);
p = strtok_r(NULL, deli, &gg);
i++;
}


if (buf != NULL)
{
free(buf);
buf = NULL;
}

return i;

}
