Networking_Proxy_SetProxyOptions Function

Header: #include <applibs/networking.h>

Sets proxy options for a Networking_ProxyConfig struct.

  int Networking_Proxy_SetProxyOptions(Networking_ProxyConfig *proxyConfig, Networking_ProxyOptions proxyOptions);

Parameters

  • proxyConfig A pointer to the Networking_ProxyConfig struct to update.

  • proxyOptions The Networking_ProxyOptions value that contains the proxy options.

Errors

If an error is encountered, returns -1 and sets errno to the error value.

  • EFAULT: The proxyConfig parameter is NULL.

Any other errno may also be specified; such errors aren't deterministic and there's no guarantee that the same behavior will be retained through system updates.

Returns

0 for success, or -1 for failure, in which case errno will be set to the error value.

Remarks

By default, the configuration settings are preserved when the proxy is disabled. There is no need to provide the settings again when the proxy is re-enabled.

Concepts and samples

The proxy code snippets demonstrate the following:

  • The Configure Proxy Settings code snippet demonstrates how to configure the proxy settings on an Azure Sphere device.
  • The Get Proxy Settings code snippet demonstrates how to retrieve the proxy settings on an Azure Sphere device.
  • The Enable/Disable Configured Proxy code snippet demonstrates how to enable/disable an already configured proxy on an Azure Sphere device.

The HTTPS samples demonstrate using the HTTPS_Curl_Easy and HTTPS_Curl_Multi APIs to fetch content over HTTPS. By default, they configure the cURL handle to use a proxy.

The AzureIoT sample contains instructions and code for adding web proxy support to the sample.
