CRYPT_PROVIDER_REGDEFUSAGE structure (wintrust.h)
The CRYPT_PROVIDER_REGDEFUSAGE structure is used by the WintrustAddDefaultForUsage function to register callback information about a provider's default usage.
Syntax
typedef struct _CRYPT_PROVIDER_REGDEFUSAGE {
DWORD cbStruct;
GUID *pgActionID;
WCHAR *pwszDllName;
char *pwszLoadCallbackDataFunctionName;
char *pwszFreeCallbackDataFunctionName;
} CRYPT_PROVIDER_REGDEFUSAGE, *PCRYPT_PROVIDER_REGDEFUSAGE;
Members
cbStruct
Size, in bytes, of this structure.
pgActionID
GUID that specifies the provider's default action.
pwszDllName
Pointer to the name of the provider DLL.
pwszLoadCallbackDataFunctionName
Pointer to the name of the function that loads the callback data to be returned when the WintrustGetDefaultForUsage function is called with the dwAction parameter set to DWACTION_ALLOCANDFILL. This information also exists in the WINTRUST_DATA structure.
pwszFreeCallbackDataFunctionName
Pointer to the name of the function that frees allocated memory when the WintrustGetDefaultForUsage function is called with the dwAction parameter set to DWACTION_FREE. This information also exists in the WINTRUST_DATA structure.
