Re : y_va problem - S4t3K - 20.06.2014

y_va isn't designed to do such things.
If you want to do it, use "format" directly. It will use the same part of memory than creating a variable in a function, formating it and returning it.

PHP код:

va_printEx(const string[], va_args<>)
{
      new out[145];
      va_format(out, sizeof(out), string, va_start<1>);
      return print(out);
}

My code just example.

Re : y_va problem - S4t3K - 20.06.2014

And mine was an answer to the problem pointed out in the example.

Re: y_va problem - KesaSport - 20.06.2014

How to return string i some similar func?

Re : y_va problem - S4t3K - 20.06.2014

Use Slice's "sprintf" function.
It's in his "strlib" include.
