  _In_     WS_WRITE_OPTION                 writeOption,
           const void*                     value,

);

writer [in]

The writer to write the attribute to.

Information about how the value is allocated. See WS_WRITE_OPTION for more information.

If the value is NULL, then the size should be 0.

Remarks

This API writes the start attribute, attribute value, and end attribute.

If the API fails, the state of input writer becomes undefined. The only APIs that may be used on the writer if this occurs are WsSetOutput and WsSetOutputToBuffer to return the writer to a usable state, or WsFreeWriter to free the writer.
