chdirhelper Function

int chdirhelper(
    BYTE mode, 
    char * ramptr, 
    const rom char * romptr
);

This helper function is used by the FSchdir function. If the path argument is specified in ROM for PIC18 this function will be able to parse it correctly. The function will loop through a switch statement to process the tokens in the path string. Dot or dotdot entries are handled in the first case statement. A backslash character is handled in the second case statement (note that this case statement will only be used if backslash is the first character in the path; backslash token delimiters will automatically be skipped after each token in the path is processed). The third case statement will handle actual directory name strings.
