This page documents the libcurl package used by official sw. This is statically linked in the main-codebin, on old versions (~v2.x) this was a subsdk NSO. This page does not apply to the libcurl build included in the browser OSS NRO.

~~With~~ sdkver 10.x, this is built with support for NGHTTP2 with the relevant [[SSL_services|Alpn]] cmds being used for this.

Starting with sdkver 10.x, this is built with support for NGHTTP2 with the relevant [[SSL_services|Alpn]] cmds being used for this.

The changes to libcurl compared to the original libcurl are documented below, etc.

== SSL_CTX_FUNCTION ==

This funcptr is called with the same params as normal, with the context ptr being {sdknso container object for [[SSL_services#ISslContext|ISslContext]]}.

This funcptr is called with the same params as normal, with the context ptr being {sdknso container object for [[SSL_services#ISslContext|ISslContext]]}. If this funcptr returns non-zero, the CURLcode is set to CURLE_ABORTED_BY_CALLBACK.

This is only used if [[#UNK502]] is not set, in which case an error is thrown if this funcptr is not set. An error is also thrown afterwards if the context wasn't created.

The user must create the [[SSL_services#ISslContext|ISslContext]] using this funcptr, with all required ISslContext initialization - no cmds are used by the caller with ISslContext besides [[SSL_services#CreateConnection|CreateConnection]].

Line 57:

A warning is printed if this option is set when CURLOPT_PROXY is already set - in which case CURLOPT_PROXY is freed.

This option controls whether to load the system proxy from [[Network_Interface_services#GetCurrentNetworkProfile|nifm]]. The code handling this option was added to the start of the inlined create_conn_helper_init_proxy func.
