optionNextValue(3)            Programmer's Manual           optionNextValue(3)



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
