convert string to enum function

[Farhad1]

I want to create a function that takes the string and returns the enum, but this function gives the following error. how can i convert string to enum?

error: begining bracket expected

enum TIMEFRAME(string timeframe)
{
  if(timeframe=="H1")        return(PERIOD_H1);
  else if(timeframe=="H4")   return(PERIOD_H4);
  else if(timeframe=="D1")   return(PERIOD_D1);   
  else                       return(PERIOD_CURRENT);
}

   Simplify your code. Stop using strings. Use the enumeration and you are done. input ENUM_TIMEFRAMES timeframe = PERIOD_D1; No function needed, no conversion needed.
