Send Feedback

This code requests a smart card reader driver to eject the currently inserted smart card from the smart card reader.

Parameters

  • dwOpenData
    [in] Handle returned from a call to the smart card reader driver's XXX_Open (Device Manager) function.
  • dwCode
    [in] Specifies this code.
  • pBufIn
    Ignored.
  • dwLenIn
    Ignored.
  • pBufOut
    [out] Pointer to the DWORD to place in the event mask. The returned mask shows the event that terminated the wait. If a process attempts to change the device handle's event mask by using the IOCTL_SERIAL_SET_WAIT_MASK call, the driver should return immediately with (DWORD) 0 as the returned event mask.
  • dwLenOut
    [out] Specifies the size of the pBufOut pointer.
  • pdwActualOut
    [out] Pointer to a DWORD to return the length of the returned data; should be set to sizeof(DWORD) if there is no error.

One of the following Status values.

Status Description
STATUS_SUCCESS Card successfully ejected.
STATUS_NO_MEDIA No card in reader.
STATUS_NOT_SUPPORTED Reader does not support card eject.
STATUS_IO_TIMEOUT Operation has timed out.

Header: Winsmcrd.h.
