FC_GetInfo - return general information about the PKCS #11 library.
CK_RV FC_GetInfo(CK_INFO_PTR pInfo);
FC_GetInfo has one parameter:
pInfoFC_GetInfo returns general information about the PKCS #11 library. On return, the CK_INFO structure that pInfo points to has the following information:
cryptokiVersion: PKCS #11 interface version number implemented by the PKCS #11 library. The version is 2.20 (major=0x02, minor=0x14).
manufacturerID: the PKCS #11 library manufacturer, "Mozilla Foundation", padded with spaces to 32 characters and not null-terminated.
flags: should be 0.
libraryDescription: description of the library, "NSS Internal Crypto Services", padded with spaces to 32 characters and not null-terminated.
libraryVersion: PKCS #11 library version number, for example, 3.11 (major=0x03, minor=0x0b).
A user may call FC_GetInfo without logging into the token (to assume the NSS User role).
FC_GetInfo always returns CKR_OK.
FC_GetInfo should return CKR_ARGUMENTS_BAD if pInfo is NULL.
FC_GetInfo should return CKR_CRYPTOKI_NOT_INITIALIZED if the library is not initialized.
Note the use of the %.32s format string to print the manufacturerID and libraryDescription members of the CK_INFO structure.
