SCARD_IO_REQUEST

  • Article

This structure begins a protocol control information structure. Any protocol-specific information then immediately follows this structure. The entire length of the structure must be aligned with the underlying hardware architecture word size. For example, in Windows CE the length of any PCI information must be a multiple of 4 bytes so that it aligns on a 32-bit boundary.

typedef struct {
  DWORD dwProtocol;
  DWORD cbPciLength;
} SCARD_IO_REQUEST;

Members

  • dwProtocol
    Identifies the protocol in use.
  • cbPciLength
    Supplies the length, in bytes, of the SCARD_IO_REQUEST structure plus any following PCI-specific information.

Requirements

OS Versions: Windows CE 3.0 and later.
Header: Winscard.h.
