This API will serialize the value of the detail field of the WS_FAULT stored in the WS_ERROR object.

This functions supports the following scenarios, based on the contents of the WS_ELEMENT_DESCRIPTION in the WS_FAULT_DETAIL_DESCRIPTION supplied:

  • Writing a single element. In this case, the elementLocalName and elementNs fields of the WS_ELEMENT_DESCRIPTION should be set to the local name and namespace of the element to write, and the type and type description represents the type of the value being serialized.
  • Writing multiple elements as a single value. In this case, the elementLocalName and elementNs fields of the WS_ELEMENT_DESCRIPTION should be set to NULL, and a WS_STRUCT_TYPE and WS_STRUCT_DESCRIPTION should be specified. Each field of the structure value being serialized should correspond to element(s) to write within the fault detail. The writeOption parameter must be either WS_WRITE_REQUIRED_VALUE or WS_WRITE_REQUIRED_POINTER.
