How to return array from function in NXC?

How to return array from function in NXC? I tried the following

string[] strsplit(string str)
{
      string parts[2] = {"1", "2"};
      return parts;
}

but I get Variable name expected. Why?

P.S. if there built-in split function I'll be glad to here about it.

Solution

  • string[] cannot be a return type in C or C++, and hence NXC.

    See the NXC API for SubStr(), to help in 'splitting' strings.

    Try:

    void strspilt(string &out[], string str, unsigned int idx)
{
    ArrayInit(out, "", 2);

    out[0] = SubStr(str, 0, idx);
    out[1] = SubStr(str, idx, strlen(str) - idx);
}
