Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

NAME
ne_addr_resolve, ne_addr_result, ne_addr_first, ne_addr_next, ne_addr_print, ne_addr_error, ne_addr_destroy - functions to resolve host- names to addresses
SYNOPSIS
#include <ne_socket.h> ne_sock_addr *ne_addr_resolve (const char *hostname, int flags); int ne_addr_result (const ne_sock_addr *addr); ne_inet_addr *ne_addr_first (ne_sock_addr *addr); ne_inet_addr *ne_addr_next (ne_sock_addr *addr); char *ne_addr_print (const ne_inet_addr *iaddr, char *buffer, size_t bufsiz); char *ne_addr_error (const ne_sock_addr *addr, char *buffer, size_t bufsiz); void ne_addr_destroy (ne_sock_addr *addr);
DESCRIPTION
The ne_addr_resolve function resolves the given hostname, returning an ne_sock_addr object representing the address (or addresses) associ- ated with the hostname. The flags parameter is currently unused, and should be passed as 0. The hostname passed to ne_addr_resolve can be a DNS hostname (e.g. www.example.com) or an IPv4 dotted quad (e.g. 192.0.34.72); or, on sys- tems which support IPv6, an IPv6 hex address, which may be enclosed in brackets, e.g. [::1]. To determine whether the hostname was successfully resolved, the ne_addr_result function is used, which returns non-zero if an error oc- curred. If an error did occur, the ne_addr_error function can be used, which will copy the error string into a given buffer (of size buf- siz. The functions ne_addr_first and ne_addr_next are used to retrieve the Internet addresses associated with an address object which has been successfully resolved. ne_addr_first returns the first address; ne_addr_next returns the next address after the most recent call to ne_ad- dr_next or ne_addr_first, or NULL if there are no more addresses. The ne_inet_addr pointer returned by these functions can be passed to ne_sock_connect to connect a socket. To return the string representation of a particular network address, the ne_addr_print function can be used. After the address object has been used, it should be destroyed using ne_addr_destroy.
RETURN VALUE
ne_addr_resolve returns a pointer to an address object, and never NULL. ne_addr_error and ne_addr_print both return the buffer parameter .
EXAMPLES
The code below prints out the set of addresses associated with the hostname www.google.com. ne_sock_addr *addr; char buf[256]; addr = ne_addr_resolve("www.google.com", 0); if (ne_addr_result(addr)) { printf("Could not resolve www.google.com: %s\n", ne_addr_error(addr, buf, sizeof buf)); } else { ne_inet_addr *ia; printf("www.google.com:"); for (ia = ne_addr_first(addr); ia != NULL; ia = ne_addr_next(addr)) { printf(" %s", ne_addr_print(ia, buf, sizeof buf)); } putchar('\n'); } ne_addr_destroy(addr);
