);
Parameters
errorcode
[in] Specifies the HRESULT that a function returned.
buf
[out] Specifies a pointer to a buffer where the error facility information is returned. Pass NULL for buf in order to determine the required buffer size.

If the function fails to recognize an error code then the return value is negative.

If the function successfully retrieves information and the parameter buf is NULL then the return value is the number of characters required to store the description (including a null-terminating character).
If the function successfully retrieves information and the parameter buf is not NULL then the return value is the number of characters written to the buffer (including a null-terminating character).
