See Also Error, GetErrorList, Status
The
GetError
command is user-called after another function returns an error indication. The device
handle sent to the function that returned the error indication is sent to
GetError
as its
devHandle
parameter.
GetError
finds the error associated with that device and returns the error code associated with
that error. If a non-null error text pointer is passed,
GetError
also fills in up to 247 bytes in the string.
The application must ensure that sufficient space is available.
