hesiod_getmailhost, hesiod_free_postoffice − Hesiod functions for retrieving user to postoffice mappings
#include <hesiod.h>
struct hesiod_postoffice *hesiod_getmailhost(void *context,
|
const char *user) |
void hesiod_free_postoffice(void *context,
|
struct hesiod_postoffice *po) |
cc file.c -lhesiod
This family of
functions allows you to retrieve user to postoffice mappings
using Hesiod. To perform lookups, you need an initialized
Hesiod context; see hesiod(3) for details. Information is
returned in a hesiod_postoffice structure, which has
the following fields:
hesiod_po_type
The type of postoffice box, typically ’’POP’’.
hesiod_po_host
The hostname where the postoffice box resides.
hesiod_po_name
The account name on the given postoffice server.
It is the caller’s responsibility to call hesiod_free_postoffice with the returned postoffice entry to free the resources used by the postoffice entry.
Hesiod queries for postoffice information are made using the ’’pobox’’ Hesiod type, using the username as the Hesiod name. The corresponding entries should be space-separated lists of strings giving the type of postoffice box, the hostname, and the account name.
On failure, hesiod_getservbyname returns NULL and sets the global variable errno to indicate the error.
hesiod_getmailhost may fail for any of the reasons the routine hesiod_resolve may fail.
