// any ".." or "." complete filenames from the URL. Writes the result into ioDest.

//If successful, returns the length of the destination string.
//If failure, returns an OS errorcode: OS_BadURLFormat, OS_NotEnoughSpace

// This function takes a character string and % encodes any special URL characters.
// In general, the output buffer will be longer than the input buffer, so caller should
// be aware of that.
//
//If successful, returns the length of the destination string.
//If failure, returns an QTSS errorcode: OS_NotEnoughSpace

// If function returns E2BIG, ioDest will be valid, but will contain
// only the portion of the URL that fit.
