Detailed Description

Macro Definition Documentation

OP_SSL_SKIP_CERTIFICATE_CHECK

#define OP_SSL_SKIP_CERTIFICATE_CHECK

(

_b

)

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

Parameters

_b	opus_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.

OP_HTTP_PROXY_HOST

#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

_host

const char *: The proxy server hostname. This may be NULL to disable the use of a proxy server.

OP_HTTP_PROXY_PORT

#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

_port

opus_int32: The proxy server port. This must be in the range 0...65535 (inclusive), or the URL function this is passed to will fail.

OP_HTTP_PROXY_USER

#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

_user

const 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.

OP_HTTP_PROXY_PASS

#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

_pass

const 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.

OP_GET_SERVER_INFO

#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

_info

OpusServerInfo *: 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

opus_server_info_clear()

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

_info

The OpusServerInfo structure to clear.
