/*
 * nssck.api
 *
 * This automatically-generated file is used to generate a set of
 * Cryptoki entry points within the object space of a Module using
 * the NSS Cryptoki Framework.
 *
 * The Module should have a .c file with the following:
 *
 *  #define MODULE_NAME name
 *  #define INSTANCE_NAME instance
 *  #include "nssck.api"
 *
 * where "name" is some module-specific name that can be used to
 * disambiguate various modules.  This included file will then
 * define the actual Cryptoki routines which pass through to the
 * Framework calls.  All routines, except C_GetFunctionList, will
 * be prefixed with the name; C_GetFunctionList will be generated
 * to return an entry-point vector with these routines.  The
 * instance specified should be the basic instance of NSSCKMDInstance.
 *
 * If, prior to including nssck.api, the .c file also specifies
 *
 *  #define DECLARE_STRICT_CRYTPOKI_NAMES
 *
 * Then a set of "stub" routines not prefixed with the name will
 * be included.  This would allow the combined module and framework
 * to be used in applications which are hard-coded to use the
 * PKCS#11 names (instead of going through the EPV).  Please note
 * that such applications should be careful resolving symbols when
 * more than one PKCS#11 module is loaded.
