CardQueryCapabilities function

This function queries the card and card-specific minidriver combination for the functionality that is provided at this level, such as certificate or file compression.

Syntax

DWORD WINAPI CardQueryCapabilities(
  _In_    PCARD_DATA           pCardData,
  _Inout_ PCARD_CAPABILITIES   pCardCapabilities
);

Parameters

• pCardData [in]
  Context information for the call. For more information, see CardAcquireContext.

• pCardCapabilities [in, out]
  Card capabilities structure with the version number set. A filled-in CARD_CAPABILITIES structure is returned.

Return value

Zero on success; otherwise, nonzero.

Remarks

Certificate files should be written to the card in a compressed state and with accompanying error-checking information. The Base CSP/KSP performs these operations if the card minidriver cannot do so. The information that this function returns indicates whether the card minidriver or card can do so.
