From 7c82870d4543f0eeb0e3a2638b083ff97b41a0fb Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Wed, 6 Jul 2016 21:15:00 -0400 Subject: [PATCH] remove obsolete and unused gethostbyaddr implementation this code was already under #if 0, but could be confusing if a reader didn't notice that, and it's almost surely full of bugs and/or inconsistencies with the current code that uses the gethostbyname2_r backend. --- src/network/gethostbyname.c | 52 ------------------------------------- 1 file changed, 52 deletions(-) diff --git a/src/network/gethostbyname.c b/src/network/gethostbyname.c index 5088a51e..bfedf52a 100644 --- a/src/network/gethostbyname.c +++ b/src/network/gethostbyname.c @@ -9,55 +9,3 @@ struct hostent *gethostbyname(const char *name) { return gethostbyname2(name, AF_INET); } - -#if 0 -struct hostent *gethostbyname(const char *name) -{ - static struct hostent h; - static char *h_aliases[3]; - static char h_canon[256]; - static char *h_addr_list[10]; - static char h_addr_data[10][4]; - static const struct addrinfo hint = { - .ai_family = AF_INET, .ai_flags = AI_CANONNAME - }; - struct addrinfo *ai, *p; - int i; - - switch (getaddrinfo(name, 0, &hint, &ai)) { - case EAI_NONAME: - h_errno = HOST_NOT_FOUND; - break; - case EAI_AGAIN: - h_errno = TRY_AGAIN; - break; - case EAI_FAIL: - h_errno = NO_RECOVERY; - break; - default: - case EAI_MEMORY: - case EAI_SYSTEM: - h_errno = NO_DATA; - break; - case 0: - break; - } - - strcpy(h_canon, ai->ai_canonname); - h.h_name = h_canon; - h.h_aliases = h_aliases; - h.h_aliases[0] = h_canon; - h.h_aliases[1] = strcmp(h_canon, name) ?
