respondd providers are C modules (shared objects). These modules should include
|
|
\<json-c/json.h> and \<respondd.h>, the latter of which provides the following definitions:
|
|
|
|
typedef struct json_object * (*respondd_provider)(void);
|
|
|
|
struct respondd_provider_info {
|
|
const char *request;
|
|
const respondd_provider provider;
|
|
};
|
|
|
|
extern const struct respondd_provider_info respondd_providers[];
|
|
|
|
|
|
The module must define the array `respondd_providers`, e.g. like this:
|
|
|
|
static struct json_object * respondd_provider_nodeinfo(void) {
|
|
...
|
|
}
|
|
|
|
static struct json_object * respondd_provider_statistics(void) {
|
|
...
|
|
}
|
|
|
|
const struct respondd_provider_info respondd_providers[] = {
|
|
{"nodeinfo", respondd_provider_nodeinfo},
|
|
{"statistics", respondd_provider_statistics},
|
|
{}
|
|
};
|
|
|
|
The array must be terminated with an empty entry. The provider for each
|
|
request type must return a [JSON-C] JSON object. This JSON object must have exactly 1
|
|
reference, and all other memory must be freed by the provider before returning.
|
|
|
|
The JSON objects returned by different provider modules for the same request type
|
|
are merged.
