SecPkgContext_Sizes (Windows CE 5.0)
This structure indicates the sizes of important structures used in the message support functions. The QueryContextAttributes function uses this structure.
typedef struct _SecPkgContext_Sizes {ULONG cbMaxToken;ULONG cbMaxSignature;ULONG cbBlockSize;ULONG cbSecurityTrailer;} SecPkgContext_Sizes, SEC_FAR *PSecPkgContext_Sizes;
Members
- cbMaxToken

Maximum size of the signature created by the MakeSignature function. This member should be zero if integrity services are not requested or available. - 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. - cbSecurityTrailer
Size of the security trailer to be appended to messages. This member should be zero if the relevant services are not requested or available.
