View source: R/gioFuncs.R

Description

Synchronously performs a DNS SRV lookup for the given service and protocol in the given domain and returns a list of GSrvTarget. domain may be an ASCII-only or UTF-8 hostname. Note also that the service and protocol arguments do not include the leading underscore that appears in the actual DNS entry.

Usage

1
2
gResolverLookupService(object, service, protocol, domain, cancellable = NULL, 
    .errwarn = TRUE)

Arguments

object

a GResolver

service

the service type to look up (eg, "ldap")

protocol

the networking protocol to use for service (eg, "tcp")

domain

the DNS domain to look up the service in

cancellable

a GCancellable, or NULL

.errwarn

Whether to issue a warning on error or fail silently

Details

On success, gResolverLookupService will return a list of GSrvTarget, sorted in order of preference. (That is, you should attempt to connect to the first target first, then the second if the first fails, etc.)

If the DNS resolution fails, error (if non-NULL) will be set to a value from GResolverError.

If cancellable is non-NULL, it can be used to cancel the operation, in which case error (if non-NULL) will be set to G_IO_ERROR_CANCELLED.

If you are planning to connect to the service, it is usually easier to create a GNetworkService and use its GSocketConnectable interface. Since 2.22

Value

A list containing the following elements:

retval

[list] a list of GSrvTarget, or NULL on error. You must free each of the targets and the list when you are done with it. (You can use gResolverFreeTargets to do this.)

error

return location for a GError, or NULL
