Re: [edk2-devel] [PATCH] RedfishPkg/JsonLib: Add JsonLoadString function
Posted by Abner Chang 3 years, 2 months ago 
It loads a JSON payload in the format of NULL terminated string to a JSON object. 
This function is used by either edk2 Redfish client applications or other edk2 modules which manipulate JSON properties.

Regards,
Abner
