Mostly, several functions that take pointers as arguments, almost
always char * pointers, had those pointers qualified with "const".
Those that returned pointers to previously const-qualified arguments
had their return values qualified as const. Some structure members
were qualified as const to retain that attribute from the variables
from which they were assigned.
The macro DE_CONST is used to deal with a handful of very special
places where something is qualified as const but really needs to have
its const qualifier removed.
rdata.c now defines macros for the prototypes of the basic rdata functions,
and all of the lib/dns/rdata/**/*.c files now use them.
Some minor integer-compatibility issues. (IE, ~0x03 is a signed int,
so assigning it to an unsigned int should use a cast. The type of an
enum member is int, so there are some conversion issues there, too.)
A pointers-to-function should not be cast to a pointer-to-object.
Variables should not be named for C reserved identifiers.
One or two set-but-not-used variables removed.
Minor other ISC style cleanups.

isc_result_t result;

Note that the first is in timer_cleanup, a function returning void in a context
that can't do anything with something other than void (as an isc_taskaction_t).
It calls isc_timer_reset, which could conceivably return ISC_R_NOMEMORY or
ISC_R_UNEXPECTED. For now the call has been cast to void, but someone
who knows the code better should have a look and see whether something more
intelligent could be done with an error (and, if not, remove my XXX and
make sure the comment is clear as to why ignoring the return is the
best that can be done).
because it was causing HP/UX to barf up eight lines of:
cc: "adb.c", line 2219: warning 509: Condition always evaluates to true: If clause will always be executed.
Cleanup of redundant/useless header file inclusion.
ISC style lint, primarily for function declarations and standalone
comments -- ie, those that appear on a line without any code, which
should be written as follows:
/*
* This is a comment.
*/
Added:
isc_buffer_base(b) (pointer)
isc_buffer_current(b) (pointer)
isc_buffer_active(b) (pointer)
isc_buffer_used(b) (pointer)
isc_buffer_length(b) (int)
isc_buffer_usedlength(b) (int)
isc_buffer_consumedlength(b) (int)
isc_buffer_remaininglength(b) (int)
isc_buffer_activelength(b) (int)
isc_buffer_availablelength(b) (int)
Removed:
ISC_BUFFER_USEDCOUNT(b)
ISC_BUFFER_AVAILABLECOUNT(b)
isc_buffer_type(b)
Changed names:
isc_buffer_used(b, r) ->
isc_buffer_usedregion(b, r)
isc_buffer_available(b, r) ->
isc_buffer_available_region(b, r)
isc_buffer_consumed(b, r) ->
isc_buffer_consumedregion(b, r)
isc_buffer_active(b, r) ->
isc_buffer_activeregion(b, r)
isc_buffer_remaining(b, r) ->
isc_buffer_remainingregion(b, r)
Buffer types were removed, so the ISC_BUFFERTYPE_*
macros are no more, and the type argument to
isc_buffer_init and isc_buffer_allocate were removed.
isc_buffer_putstr is now void (instead of isc_result_t)
and requires that the caller ensure that there
is enough available buffer space for the string.
Preliminary support for the "target" attribute of the adbname, to be used
for CNAME/DNAME chains later on.
The resolver will now do appropriate findzonecut calls, so the ADB need
not concern itself with them any more.
Fix some bugs in NXDOMAIN/NXRRSET handling.
