Description

Details

soup_dns_entry_from_name ()

SoupDNSEntry* soup_dns_entry_from_name      (const char *name);

Begins asynchronous resolution of name. The caller should periodically call soup_dns_entry_check_lookup() to see if it is done, and call soup_dns_entry_get_hostent() when soup_dns_entry_check_lookup() returns TRUE.

Currently, this routine forks and does the lookup, which can cause some problems. In general, this will work ok for most programs most of the time. It will be slow or even fail when using operating systems that copy the entire process when forking.

name : a nice name (eg, mofo.eecs.umich.edu) or a dotted decimal name (eg, 141.213.8.59).
Returns : a SoupDNSEntry, which will be freed when you call soup_dns_entry_get_hostent() or soup_dns_entry_cancel_lookup().

soup_dns_entry_from_addr ()

SoupDNSEntry* soup_dns_entry_from_addr      (gconstpointer addr,
                                             int family);

Begins asynchronous resolution of addr. The caller should periodically call soup_dns_entry_check_lookup() to see if it is done, and call soup_dns_entry_get_hostent() when soup_dns_entry_check_lookup() returns TRUE.

Currently, this routine forks and does the lookup, which can cause some problems. In general, this will work ok for most programs most of the time. It will be slow or even fail when using operating systems that copy the entire process when forking.

addr : pointer to address data (eg, an in_addr_t)
family : address family of addr
Returns : a SoupDNSEntry, which will be freed when you call soup_dns_entry_get_hostent() or soup_dns_entry_cancel_lookup().

soup_dns_entry_check_lookup ()

gboolean    soup_dns_entry_check_lookup     (SoupDNSEntry *entry);

Checks if entry has finished resolving

entry : a SoupDNSEntry
Returns : TRUE if entry has finished resolving (either successfully or not)

soup_dns_entry_cancel_lookup ()

void        soup_dns_entry_cancel_lookup    (SoupDNSEntry *entry);

Cancels the lookup for entry.

entry : a SoupDNSEntry

soup_dns_free_hostent ()

void        soup_dns_free_hostent           (struct hostent *h);

Frees h. Use this to free the return value from soup_dns_entry_get_hostent().

h : a hostent

soup_dns_ntop ()

char*       soup_dns_ntop                   (gconstpointer addr,
                                             int family);

Converts addr into textual form (eg, "141.213.8.59"), like the standard library function inet_ntop(), except that the returned string must be freed.

addr : pointer to address data (eg, an in_addr_t)
family : address family of addr
Returns : the text form or addr, which must be freed.
