SECURITY_STATUS SEC_ENTRY SetCredentialsAttributesA(
[in] PCredHandle phCredential,
[in] unsigned long ulAttribute,
[in] void *pBuffer,
unsigned long cbBuffer
);
Parameters

A handle of the credentials to be set.
[in] ulAttribute

Remarks
Note
The sspi.h header defines SetCredentialsAttributes as an alias which 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 not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
