NAME

       hesiod_getmailhost,  hesiod_free_postoffice  -  Hesiod  functions  for  retrieving user to
       postoffice mappings

SYNOPSIS

       #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

DESCRIPTION

       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.

RETURN VALUES

       On  failure,  hesiod_getservbyname  returns  NULL  and  sets  the global variable errno to
       indicate the error.

ERRORS

       hesiod_getmailhost may fail for any of the reasons the routine hesiod_resolve may fail.
