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);
