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

Runs on Versions Defined in Include Link to
Windows CE OS 3.0 and later Winscard.h    

Note   This API is part of the complete Windows CE OS package as provided by Microsoft. The functionality of a particular platform is determined by the original equipment manufacturer (OEM) and some devices may not support this API.
