PDL_GetParamInt

Description

Extracts a named int parameter passed to a service callback function. You can register a callback function with a service using the PDL_ServiceCallWithCallback API. All parameters are passed as strings, though their underlying types (string, double, or int) can be different.

This API returns 0 if the parameter is not found. You can use the PDL_ParamExists API to check if the parameter exists before calling this API.

See Accessing Services for more information and examples.

Syntax

int PDL_GetParamInt(PDL_ServiceParameters *params, const char *name);     

Argument Description
params Parameters from which to extract data. This is passed to the callback function from the service and you simply pass it on here without modification.
name Name of the argument to extract.

Returns

passed int, or 0 if the parameter doesn't exist.
