/*
* Get the maximum limit for a system resource.
*
* Notes:
* ISC_RESOURCE_UNLIMITED is the maximum value of isc_resourcevalue_t.
*
* On many (all?) Unix systems, RLIM_INFINITY is a valid value that is
* significantly less than ISC_RESOURCE_UNLIMITED, but which in practice
* behaves the same.
*
* The current ISC libdns configuration file parser assigns a value
* of ISC_UINT32_MAX for a size_spec of "unlimited" and ISC_UNIT32_MAX - 1
* for "default", the latter of which is supposed to represent "the
* limit that was in force when the server started". Since these are
* valid values in the middle of the range of isc_resourcevalue_t,
* there is the possibility for confusion over what exactly those
* particular values are supposed to represent in a particular context --
* discrete integral values or generalized concepts.
*
* Requires:
* 'resource' is a valid member of the isc_resource_t enumeration.
*
* Returns:
* The current setting of the maximum limit for a system resource.
