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.
