/*
**  NI_PROPVAL -- NetInfo property value lookup routine
**
**	Parameters:
**		keydir -- the NetInfo directory name in which to search
**			for the key.
**		keyprop -- the name of the property in which to find the
**			property we are interested.  Defaults to "name".
**		keyval -- the value for which we are really searching.
**		valprop -- the property name for the value in which we
**			are interested.
**		sepchar -- if non-nil, this can be multiple-valued, and
**			we should return a string separated by this
**			character.
**
**	Returns:
**		NULL -- if:
**			1. the directory is not found
**			2. the property name is not found
**			3. the property contains multiple values
**			4. some error occurred
**		else -- the value of the lookup.
**
**	Example:
**		To search for an alias value, use:
**		  ni_propval("/aliases", "name", aliasname, "members", ',')
**
**	Notes:
**		Caller should free the return value of ni_proval
