Hi Antoine,

This is code of that function:

bool FBL_WordArray::GetWord( const char*& pWord, const char*& pWordEnd )
{
    if( pWordEnd )
    {
        if( *pWordEnd == 0 )            // we are at end of string
                return false;
        else    pWord = pWordEnd + 1;     // set pointer to the begin of
next word
    }
    else
    {
        if( *pWord == 0 )                // empty string
            return false;
    }
    
    while( *pWord && !isalnum(uchar(*pWord)) )
        pWord++;

    if( *pWord == 0 )    // there is no more words
        return false;

    pWordEnd = pWord;

    while( *pWordEnd && isalnum(uchar(*pWordEnd)) )
        pWordEnd++;    // loking space character.

    return true;

}  /* FBL_WordArray::GetWord */
