Inputs

The inputs to this function are:

requestID-A pointer to an AsyncRequest ID field that receives the unique ID associated with the outstanding asynchronous request. The returned AsyncRequestID is used on subsequent API calls to refer to a specific outstanding asynchronous request.
noResponse-A flag used to inform the supporting runtime if the application wishes to process the response associated with the request being initiated.
A value of NORESPONSE causes the supporting runtime to mark the request as complete before returning control back to the initiating runtime. In this case, the application does not need to explicitly complete the request using either a ProxyGetAsyncResponse or ProxyIgnoreAsyncResponse.

A value of RESPONSE causes the supporting runtime to treat the request as a cooperative flow, such that the application expects to process the request's corresponding response.
Tran-A pointer to a completed TranEntry data structure. The import view referenced in the specified TranEntry is used by ProxyExecuteAsync to formulate the asynchronous request.
param-A pointer to an allocated (and completed) ProxyParam data structure.
errMsg-A pointer to a character array buffer that is populated with an error message if the asynchronous request is not accepted by the supporting runtime.
errMsgLen-An integer value that specifies the size of the errMsg character array.
