NAME

       optionNextValue - get the next value from a hierarchical list

SYNOPSIS

       #include <your-opts.h>
       cc [...] -o outfile infile.c -lopts [...]

       const  tOptionValue * optionNextValue(const tOptionValue * pOptValue, const tOptionValue *
       pOldValue);

DESCRIPTION

       This routine will return the next entry after the entry passed in.   At  the  end  of  the
       list, NULL will be returned.  If the entry is not found on the list, NULL will be returned
       and "errno" will be set to EINVAL.  The "pOldValue" must have been  gotten  from  a  prior
       call to this routine or to "opitonGetValue()".

       pOptValue
              a hierarchcal list value

       pOldValue
              a value from this list

RETURN VALUE

       a compound value structure

ERRORS

       The returned result is NULL and errno is set:

       EINVAL  -  the  pOptValue does not point to a valid hierarchical option value or pOldValue
       does not point to a member of that option value.

       ENOENT - the supplied pOldValue pointed to the last entry.  @end itemize
