Macro: LMIC_C_ASSERT()
Function:
Declaration-like macro that will cause a compile error if arg is FALSE.
Definition:
LMIC_C_ASSERT(
BOOL fErrorIfFalse
);
Description:
This macro, if used where an external reference declarataion is
permitted, will either compile cleanly, or will cause a compilation
error. The results of using this macro where a declaration is not
permitted are unspecified.
This is different from #if !(fErrorIfFalse) / #error in that the
expression is evaluated by the compiler rather than by the pre-
processor. Therefore things like sizeof() can be used.
Returns:
No explicit result -- either compiles cleanly or causes a compile
error.

/*
Macro: LMIC_ABI_STD
Index: Macro: LMIC_ABI_VARARGS
Function:
Annotation macros to force a particular binary calling sequence.
Definition:
#define LMIC_ABI_STD compiler-specific
#define LMIC_ABI_VARARGS compiler-specific
Description:
These macros are used when declaring a function type, and indicate
that a particular calling sequence is to be used. They are normally
used between the type portion of the function declaration and the
name of the function. For example:
typedef void LMIC_ABI_STD myCallBack_t(void);
It's important to use this in libraries on platforms with multiple
calling sequences, because different components can be compiled with
different defaults.
Returns:
Not applicable.
