Macro Definition Documentation

KER_CTX

#define KER_CTX

When using KER_CTX_CUSTOM, this needs to be defined as the name of the context data followed by a comma, e.g.:

#define KER_CTX pTerminalContext, 

This should always be included in the parameter list when calling a function that has KER_CTX_PARAM defined in the parameter list, e.g.:

ulResult = kerFunction(KER_CTX EMV_TR 100, 0); 

KER_CTX_INIT

#define KER_CTX_INIT

When using KER_CTX_CUSTOM, this needs to be defined as the name of the pointer to obtain context data , e.g.:

#define KER_CTX_INIT ppTerminalContext 

This should always be included in the parameter list when calling a function that has KER_CTX_INIT_PARAM defined in the parameter list.

KER_CTX_INIT_DECL

#define KER_CTX_INIT_DECL

(

)

When using KER_CTX_CUSTOM, this needs to be defined as a statement that declares empty context as local variable , e.g.:

#define KER_CTX_INIT_DECL() void* pTerminalContext = KER_NULL; 

KER_CTX_INIT_PARAM

#define KER_CTX_INIT_PARAM

When using KER_CTX_CUSTOM, this needs to be defined as the name and type of the context data , e.g.:

#define KER_CTX_INIT_PARAM void** ppTerminalContext 

KER_CTX_INIT_SET

#define KER_CTX_INIT_SET

(

)

When using KER_CTX_CUSTOM, this needs to be defined as a set of statements that assignes allocated context to local variable , e.g.:

#define KER_CTX_INIT_SET()    do {if (ppTerminalContext != KER_NULL) pTerminalContext = *ppTerminalContext;}while(0) 

KER_CTX_PARAM

#define KER_CTX_PARAM

When using KER_CTX_CUSTOM, this needs to be defined as the name and type of the context data followed by a comma , e.g.:

#define KER_CTX_PARAM void* pTerminalContext, 

KER_CTX_SINGLE

#define KER_CTX_SINGLE

When using KER_CTX_CUSTOM, this needs to be defined as the name of the context data , e.g.:

#define KER_CTX_SINGLE pTerminalContext 

This should always be included in the parameter list when calling a function that has KER_CTX_SINGLE_PARAM defined in the parameter list.

KER_CTX_SINGLE_PARAM

#define KER_CTX_SINGLE_PARAM   void

When using KER_CTX_CUSTOM, this needs to be defined as the name and type of the context data , e.g.:

#define KER_CTX_SINGLE_PARAM void* pTerminalContext 

KER_CTX_TYPE

#define KER_CTX_TYPE

When using KER_CTX_CUSTOM, this needs to be defined as the type of the context data , e.g.:

#define KER_CTX_TYPE void*
