PDL_GetParamJson
Description
Used during a service callback. The callback function is passed a parms
parameter. This API takes that parameter and returns a JSON-formatted string. This is for callbacks that are expecting something more involved than int
, double
, boolean
, or string
values.
The returned pointer is only valid during the callback function. It points to internal memory; do not attempt to free or modify it.
See Accessing Services for more information on service callbacks.
Syntax
const char *PDL_GetParamJson(PDL_ServiceParameters *parms);
