It can be switched on by defining + CRYPTOKI_GNU before including this header file. For this, the + following changes are made to the specification: + + All structure types are changed to a "struct ck_foo" where CK_FOO + is the type name in PKCS #11. + + All non-structure types are changed to ck_foo_t where CK_FOO is the + lowercase version of the type name in PKCS #11. The basic types + (CK_ULONG et al.) are removed without substitute. + + All members of structures are modified in the following way: Type + indication prefixes are removed, and underscore characters are + inserted before words. Then the result is lowercased. + + Note that function names are still in the original case, as they + need for ABI compatibility. + + CK_FALSE, CK_TRUE and NULL_PTR are removed without substitute. Use + <stdbool.h>. + + If CRYPTOKI_COMPAT is defined before including this header file, + then none of the API changes above take place, and the API is the + one defined by the PKCS #11 standard. */ + +#ifndef PKCS11_H +#define PKCS11_H 1 + +#if defined(__cplusplus) +extern "C" { +#endif + + +/* The version of cryptoki we implement.
