Detailed Description

Internal stuff that cannot be easity grouped into other modules.

Macro Definition Documentation

ADD_VOID_PTR

#define ADD_VOID_PTR	(		ptr,
			nBytes
	)		( ( (uint8_t*) (ptr) ) + (nBytes) )

Add nBytes bytes to the void*

CLAMP

#define CLAMP	(		min,
			max,
			value
	)

Value:

    ( \
        (value < min) ? \
            (min) : \
            (value > max) ? \
                (max) : \
                (value) \
    )

Clamp the value between min and max

Returns

min, if value < min; max, if value > max; value otherwise

FRACTIONAL

#define FRACTIONAL

(

x

)

( (x) - floor(x) )

Get the fractional part of float or double

INDEX_VOID_PTR

#define INDEX_VOID_PTR	(		ptr,
			idx,
			nBytesPerElement
	)		( ( (uint8_t*) (ptr) ) + (idx) * (nBytesPerElement) )

Index void* as if it was an array with nBytesPerElement bytes per element

MAX

#define MAX	(		a,
			b
	)		( (a) > (b) ? (a) : (b) )

Get the maximum of two values

MIN

#define MIN	(		a,
			b
	)		( (a) > (b) ? (b) : (a) )

Get the minimum of two values
