Since the Easy Publish and Consume library hides the details of the transport mechanism used, it is possible to support different mechanisms. Currently there is support for HTTP and HTTPS.
The EpcProtocol enumeration is the maximum of information libepc wants to expose regarding its transport mechanisms.
typedef enum {
EPC_PROTOCOL_UNKNOWN,
EPC_PROTOCOL_HTTP,
EPC_PROTOCOL_HTTPS
} EpcProtocol;
The transport protocols supported by libepc.
| Used when the transport protocol is not known yet. | |
| Plain HTTP. Passwords are protected using HTTP digest authentication, remaining data is transfered without any encryption. | |
| Encrypted HTTP. Attempts are made to use this transport method when ever possible. |
EpcProtocol epc_protocol_from_name (const gchar *name,EpcProtocol fallback);
Parses the protocol name. Case of the name doesn't matter. Returns the
matching EpcProtocol, when the name was recognized, and the value of
fallback otherwise.
|
a protocol name |
|
the EpcProtocol to use on errors |
Returns : |
The EpcProtocol matching name, or fallback on error. |
gchar * epc_protocol_build_uri (EpcProtocol protocol,const gchar *hostname,guint16 port,const gchar *path);
Builds the Unified Resource Identifier (URI) for a service. The returned string should be released when no longer needed.
|
a EpcProtocol |
|
the host to contact |
|
the service port |
|
the service path, or NULL
|
Returns : |
A newly allocated string with the URI for the service,
or NULL on error. |
const gchar * epc_protocol_get_service_type (EpcProtocol protocol);
Queries the DNS-SD service type associated with a EpcProtocol. See EPC_SERVICE_TYPE_HTTP, EPC_SERVICE_TYPE_HTTPS.
|
a EpcProtocol |
Returns : |
Returns the DNS-SD service type associated
with protocol, or NULL on unknown protocols. |
const gchar * epc_protocol_get_uri_scheme (EpcProtocol protocol);
Queries the URI scheme associated with a EpcProtocol.
See epc_service_type_build_uri().
|
a EpcProtocol |
Returns : |
Returns the URI scheme associated with protocol,
or NULL on unknown protocols. |
GEnumClass * epc_protocol_get_class (void);
Retrieves the GEnumClass describing the EpcProtocol enum.
Returns : |
The GEnumClass describing EpcProtocol. |
const gchar * epc_protocol_to_string (EpcProtocol value);
Retrieves the name of a EpcProtocol value, or NULL when value is invalid.
|
a EpcProtocol value |
Returns : |
The string representation of value, or NULL. |
