SecPkgContext_StreamSizes (Windows Embedded CE 6.0)

1/6/2010

This structure indicates the sizes of the various stream parts for use with the message support functions. The QueryContextAttributes function uses this structure.

Syntax

typedef struct _SecPkgContext_StreamSizes {
  unsigned long cbHeader;
  unsigned long cbTrailer;
  unsigned long cbMaximumMessage;
  unsigned long cBuffers;
  unsigned long cbBlockSize;
}SecPkgContext_StreamSizes, *PSecPkgContext_StreamSizes;

Members

• cbHeader
  Size, in bytes, of the header portion. If zero, no header is used.

• cbTrailer
  Size, in bytes, of the trailer portion. If zero, no trailer is used.

• cbMaximumMessage
  Size, in bytes, of the largest message that can be encapsulated.

• cBuffers
  Number of buffers to pass.

• cbBlockSize
  Preferred integral size of the messages. For example, 8 indicates that messages should be of size 0 mod 8 for optimal performance. Messages other than this block size can be padded.
