#define XN_CHECK_INPUT_OVERFLOW (   x,
 
)
Value:
if (x > y) \
{ \
return (XN_STATUS_INPUT_BUFFER_OVERFLOW); \
}

Returns an output overflow error if x is beyond y

#define XN_CHECK_OUTPUT_OVERFLOW (   x,
 
)
Value:
if (x > y) \
{ \
return (XN_STATUS_OUTPUT_BUFFER_OVERFLOW); \
}

Returns an input overflow error if x is beyond y

#define XN_DISABLE_COPY_AND_ASSIGN (   TypeName)
Value:
TypeName(const TypeName&); \
void operator=(const TypeName&);

Disables Copy ctor and assignment operator. Should be placed under "private:" section.

#define XN_GOCLEANUP_RET (   x,
 
)
Value:
x = y; \
goto ErrorCleanUp;

Jumps to the ErrorCleanUp label if X isn't XN_STATUS_OK and returns Y.

#define XN_IS_BOOL_OK_GOCLEANUP_RET (   x,
 
)
Value:
if (x != TRUE) \
{ \
goto ErrorCleanUp; \
}

Jumps to the ErrorCleanUp label if X isn't XN_STATUS_OK and returns Y.

#define XN_IS_BOOL_OK_RET (   x,
 
)
Value:
if (x != TRUE) \
{ \
return (y); \
}

Returns Y if X isn't XN_STATUS_OK.

#define XN_IS_STATUS_OK (   x)    XN_IS_STATUS_OK_RET(x, x)

Returns X if X isn't XN_STATUS_OK.

#define XN_IS_STATUS_OK_ASSERT (   x)
Value:
if (x != XN_STATUS_OK) \
{ \
XN_ASSERT(FALSE); \
return (x); \
}
#define XN_IS_STATUS_OK_GOCLEANUP (   x)
Value:
if (x != XN_STATUS_OK) \
{ \
goto ErrorCleanUp; \
}

Jumps to the ErrorCleanUp label if X isn't XN_STATUS_OK.

#define XN_IS_STATUS_OK_GOCLEANUP_RET (   x,
 
)
Value:
if (x != XN_STATUS_OK) \
{ \
x = y; \
goto ErrorCleanUp; \
}

Jumps to the ErrorCleanUp label if X isn't XN_STATUS_OK and return Y.

#define XN_IS_STATUS_OK_RET (   x,
 
)
Value:
if (x != XN_STATUS_OK) \
{ \
return (y); \
}

Returns Y if X isn't XN_STATUS_OK.

#define XN_REFERENCE_VARIABLE (   x)    ((void)x)

Disables the "local variable is initialized but not referenced" warning (if you need to use this variable in an assert

#define XN_RET_IF_NULL (   x,
 
)
Value:
if (x == NULL) \
{ \
return (y); \
}

Returns Y if X is NULL.

#define XN_SETBITMASK (   x)    (1 << x-1)

Returns the (x)th power of 2.

#define XN_VALIDATE_PTR (   x,
 
)
Value:
if (x == NULL) \
{ \
return (y); \
}

Returns Y if X is null.
