Agnos provides a set of EMV core primitives which support EMV transaction flow. These primitives are used by:
CT payment applications (see emvco.c as example)
CL card processing applications (alias CL kernels)
C Structures
tTransactionalContext (agnos.h)
tADFList (selection.h)
tADF (selection.h)
tPSE (selection.h)
Callbacks
typedef void (*tGetDataCallback)(tBoolean lastRead, tBoolean *next)
typedef void (*tBuildDOLCallback)(tWord tag, tByte length, tByte *DOLData)
typedef void (*tStateCallback)(tAgnosState currentState, tBoolean *stop, tBoolean *bypass)
