  • Article

The SecPkgContext_NegotiationInfo structure contains information on the security package that is being set up or has been set up, and also gives the status on the negotiation to set up the security package.

Syntax

typedef struct _SecPkgContext_NegotiationInfoW {
  PSecPkgInfoW  PackageInfo;
  unsigned long NegotiationState;
} SecPkgContext_NegotiationInfoW, *PSecPkgContext_NegotiationInfoW;

Members

PackageInfo

Pointer to a SecPkgInfo structure that provides general information about the security package chosen in the negotiate process, such as the name and capabilities of the package.

NegotiationState

Indicator of the state of the negotiation for the security package identified in the PackageInfo member. This attribute can be queried from the context handle before the setup is complete, such as when ISC returns SEC_I_CONTINUE_NEEDED.

The following table shows values returned in this member.

Value Meaning
SECPKG_NEGOTIATION_COMPLETE
 Negotiation has been completed.
SECPKG_NEGOTIATION_OPTIMISTIC
 Negotiations not yet completed.
SECPKG_NEGOTIATION_IN_PROGRESS
 Negotiations in progress.

Remarks

Note

The sspi.h header defines SecPkgContext_NegotiationInfo as an alias that automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
