URL reading options

Options for op_url_stream_create() and associated functions.

These allow you to provide proxy configuration parameters, skip SSL certificate checks, etc. Options are processed in order, and if the same option is passed multiple times, only the value specified by the last occurrence has an effect (unless otherwise specified). They may be expanded in the future.

Detailed Description

Macro Definition Documentation

#define OP_SSL_SKIP_CERTIFICATE_CHECK (   _b)

Skip the certificate check when connecting via TLS/SSL (https).

Parameters
_bopus_int32: Whether or not to skip the certificate check. The check will be skipped if _b is non-zero, and will not be skipped if _b is zero.
#define OP_HTTP_PROXY_HOST (   _host)

Proxy connections through the given host.

If no port is specified via OP_HTTP_PROXY_PORT, the port number defaults to 8080 (http-alt). All proxy parameters are ignored for non-http and non-https URLs.

Parameters
_hostconst char *: The proxy server hostname. This may be NULL to disable the use of a proxy server.
#define OP_HTTP_PROXY_PORT (   _port)

Use the given port when proxying connections.

This option only has an effect if OP_HTTP_PROXY_HOST is specified with a non-NULL _host. If this option is not provided, the proxy port number defaults to 8080 (http-alt). All proxy parameters are ignored for non-http and non-https URLs.

Parameters
_portopus_int32: The proxy server port. This must be in the range 0...65535 (inclusive), or the URL function this is passed to will fail.
#define OP_HTTP_PROXY_USER (   _user)

Use the given user name for authentication when proxying connections.

All proxy parameters are ignored for non-http and non-https URLs.

Parameters
_userconst char *: The proxy server user name. This may be NULL to disable proxy authentication. A non-NULL value only has an effect if OP_HTTP_PROXY_HOST and OP_HTTP_PROXY_PASS are also specified with non-NULL arguments.
#define OP_HTTP_PROXY_PASS (   _pass)

Use the given password for authentication when proxying connections.

All proxy parameters are ignored for non-http and non-https URLs.

Parameters
_passconst char *: The proxy server password. This may be NULL to disable proxy authentication. A non-NULL value only has an effect if OP_HTTP_PROXY_HOST and OP_HTTP_PROXY_USER are also specified with non-NULL arguments.
#define OP_GET_SERVER_INFO (   _info)

Parse information about the streaming server (if any) and return it.

Very little validation is done. In particular, OpusServerInfo::url may not be a valid URL, OpusServerInfo::bitrate_kbps may not really be in kbps, and OpusServerInfo::content_type may not be a valid MIME type. The character set of the string fields is not specified anywhere, and should not be assumed to be valid UTF-8.

Parameters
_infoOpusServerInfo *: Returns information about the server. If there is any error opening the stream, the contents of this structure remain unmodified. On success, fills in the structure with the server information that was available, if any. After a successful return, the contents of this structure should be freed by calling opus_server_info_clear().

Function Documentation

void opus_server_info_init ( OpusServerInfo _info)

Initializes an OpusServerInfo structure.

All fields are set as if the corresponding header was not available.

Parameters

void opus_server_info_clear ( OpusServerInfo _info)

Clears the OpusServerInfo structure.

This should be called on an OpusServerInfo structure after it is no longer needed. It will free all memory used by the structure members.

Parameters
_infoThe OpusServerInfo structure to clear.
