    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.
