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 Embedded CE the length of any PCI information must be a multiple of 4 bytes so that it aligns on a 32-bit boundary.

Syntax 

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_REQUESTstructure plus any following PCI-specific information.
