56c6301089 dns.c: change dns_send/dns_recv to operate on pbuf, not on contiguous buffer -> dns_payload_buffer/DNS_MSG_SIZE can be removed 2014-09-16 19:33:20 +02:00

03bd61c799 DNS_LOCAL_HOSTLIST_IS_DYNAMIC uses its own MEMP pool instead of the heap 2010-05-16 13:36:51 +00:00
goldsimon
a54bb7205d Added missing casts, use strlen + MEMCPY instead of strcpy (as that might overrun the buffer) 2010-03-16 15:14:14 +00:00

8908055b63 Revert my last changes and remove structure packing from struct dns_query and struct dns_answer since they are only used with SMEMCPY 2010-02-14 14:02:05 +00:00

5d360a6711 Replaced struct ip_addr by typedef ip_addr_t to make changing the actual implementation behind the typedef easier. 2010-02-04 18:47:44 +00:00
goldsimon
a23b446ddf Use macros defined in ip_addr.h (some of them new) to work with IP addresses (preparation for bug #27352 - Change ip_addr from struct to typedef (u32_t) - and better code). 2010-02-04 17:21:32 +00:00

9ff7d29696 Fixed compiler warnings when MEM_SIZE < 64000 2010-02-02 20:14:05 +00:00
goldsimon
5fa0347e64 Cleanly separate the portability file inet.h and its contents from the stack: moved htonX- functions to def.h (and the new def.c - they are not ipv4 dependent), let inet.h depend on ip_addr.h and not the other way round. This fixes bug #28732. 2010-01-29 08:20:32 +00:00

c752e5731c Worked on dns: local host-list can be put into FLASH (by defining storage target/linker section), external function can be defined for lookup, combined dns_local_removehostname/removehostaddr to dns_local_removehost 2009-05-07 15:27:02 +00:00
goldsimon
c3f7107e2b Fixed some issues with DNS_LOCAL_HOSTLIST 2009-04-23 16:54:30 +00:00

goldsimon
b3c52f574a Added function documentation to dns.c, removed function documentation from dns.h (functions should be documented where they are implemented!), dns_table_entry doesn't have to be packed (slower, bigger code for most machines), converted dns_init to return void, dns_table is implicitly initialized to zero, dns_lookup can be static, dns_send returns correct error values, added some asserts, compacted dns_recv using some (ugly) gotos, compacted dns_gethostbyname by combining the same return value 2007-11-20 20:28:01 +00:00
