CC3220SF-LAUNCHXL: Max Size of int32 in JSON Library

Hi All,

When using the TI JSON library it is possible to specify "int32" as the data type for a field. Will this work as expected?

unsigned long int value;

int valueSize = sizeof(value);

ret = Json_getValue(objectHandle, "\"a\".\"b\"", &value, &valueSize);

My concern is a) about the signage, and b) if it is a full 32 bit int. I've tried it with "int" as the storage data type and got no errors. 

Thanks!
