David Drysdale	f1bcfa1122	api: Allow injection of user-specified malloc/free functions Add a new ares_library_init_mem() initialization function for the library which allows the library user to specify their own malloc, realloc & free equivalents for use library-wide. Store these function pointers in library-wide global variables, defaulting to libc's malloc(), realloc() and free(). Change all calls to malloc, realloc and free to use the function pointer instead. Also ensure that ares_strdup() is always available (even if the local environment includes strdup(3)), and change the library code to always use it. Convert calls to calloc() to use ares_malloc() + memset	9 years ago
David Drysdale	87ff25049c	Mark unhittable lines Add comments for the benefit of the lcov tool, marking lines that cannot be hit. Typically these are fall-back protection arms that are already covered by earlier checks, and so it's not worth taking out the unhittable code (in case someone changes the code between the two places in future).	9 years ago
Daniel Stenberg	cf7ad9758d	ares_inet_pton/ntop: cleanup Make sure that the symbols are always exported and present in c-ares. Make the headers prefixed with 'ares'. Removed the inet_ntop.h version as it no longer features any content.	12 years ago
Yang Tse	0c677f578e	setup_once.h: refactor inclusion of <unistd.h> and <sys/socket.h> Inclusion of these two header files now done in setup_once.h	12 years ago

Yang Tse	c2d3e82931	Overhauled ares__get_hostent() - Fixing out of bounds memory overwrite triggered with malformed /etc/hosts file. - Improving parsing of /etc/hosts file. - Validating requested address family. - Ensuring that failures always return a NULL pointer. - Adjusting header inclusions.	15 years ago
Yang Tse	737707bf4b	fix compiler warning: implicit conversion shortens 64-bit value into a 32-bit value	16 years ago
Daniel Stenberg	1ce8e6583e	- ares_gethostbyname() now accepts 'AF_UNSPEC' as a family for resolving either AF_INET6 or AF_INET. It works by accepting any of the looksups in the hosts file, and it resolves the AAAA field with a fallback to A.	16 years ago
Yang Tse	f2582d6949	include header file only when available	16 years ago
Yang Tse	2cb5cbba34	move inclusion of ares_private.h last	16 years ago
Daniel Stenberg	4e27354b82	Ashish Sharma provided a patch for supporting multiple entries in the /etc/hosts file. Patch edited for coding style and functionality by me (Daniel).	18 years ago
Gisle Vanem	a627160041	Removed inclusion of <sys/types.h> in .c-files since it's already included through "setup.h".	18 years ago

Gisle Vanem	6deb40acac	Changes for Watt-32 on Windows. I've assumed Configure sets the required HAVE_xx defines for non-DOS/Win targets.	21 years ago
Daniel Stenberg	d5f3636a52	- Fixed a few variable return types for some system calls. Made configure check for ssize_t to make it possible to use that when receiving the send() error code. This is necessary to prevent compiler warnings on some systems. - Made configure create config.h, and all source files now include setup.h that might include the proper config.h (or a handicrafted alternative). - Switched to 'ares_socket_t' type for sockets in ares, since Windows don't use 'int' for that. - automake-ified and libool-ified c-ares. Now it builds libcares as a shared lib on most platforms if wanted. (This bloated the size of the release archive with another 200K!) - Makefile.am now uses Makefile.inc for the c sources, h headers and man pages, to make it easier for other makefiles to use the exact same set of files. - Adjusted 'maketgz' to use the new automake magic when building distribution archives.	21 years ago
