  There are no built in functions for this, not sure why. You have to include <propeller.h> in your program. It would also help if you show us your code, meaning, what have you tried so far.

  #include <propeller.h>
  
  void high(int WCpin)
  {
      unsigned int bits = 1 << WCpin;
      DIRA |= bits;
      OUTA |= bits;
  }
  
  void low(int WCpin)
  {
      unsigned int mask = 1 << WCpin;
      DIRA |= mask;
      OUTA &= ~mask;
  }

  I must of scared the OP with my terse answer, so here is how it is done.

  /**
   * @file basicLED.c
   * This is the main basicLED program start point.
   */
  #include <propeller.h>
  
  
  void high(int WCpin)
  {
      unsigned int bits = 1 << WCpin;
      DIRA |= bits;
      OUTA |= bits;
  }
  
  void low(int WCpin)
  {
      unsigned int mask = 1 << WCpin;
      DIRA |= mask;
      OUTA &= ~mask;
  }
  
  /**
   * Main program function.
   */
  int main(void)
  {
      high(0);
      sleep(1);
      low(0);
      high(1);
      sleep(1);
      low(1);
      return 0;
  }
