Function Documentation

uint8 Image::Indeo::avClipUint8 ( int a ) [inline]

Clip a signed integer value into the 0-255 range.

Parameters:

a

value to clip

Returns:: clipped value

Definition at line 85 of file mem.h.

unsigned Image::Indeo::avClipUintp2	(	int	a,
		int	p
	)			`[inline]`

Clip a signed integer to an unsigned power of two range.

Parameters:

	a	value to clip
	p	bit position to clip at

Returns:: clipped value

Definition at line 98 of file mem.h.

void Image::Indeo::avFreeP ( void * arg )

Free a memory block which has been allocated with a function of av_malloc() or av_realloc() family, and set the pointer pointing to it to `NULL`.

Parameters:

ptr

Pointer to the pointer to the memory block which should be freed

Note:: `*ptr = NULL` is safe and leads to no action.

void * Image::Indeo::avReallocF	(	void *	ptr,
		size_t	nelem,
		size_t	elsize
	)

Allocate, reallocate, or free a block of memory.

This function does the same thing as av_realloc(), except:

It takes two size arguments and allocates `nelem * elsize` bytes, after checking the result of the multiplication for integer overflow.
It frees the input block in case of failure, thus avoiding the memory leak with the classic
```
 {.c}
   buf = realloc(buf);
   if (!buf)
       return -1;
```
pattern.

static int Image::Indeo::avSizeMult	(	size_t	a,
		size_t	b,
		size_t *	r
	)			`[inline, static]`

Multiply two `size_t` values checking for overflow.

Parameters:

`[in]`	a,b	Operands of multiplication
`[out]`	r	Pointer to the result of the operation

Returns:: 0 on success, AVERROR(EINVAL) on overflow

Definition at line 73 of file mem.cpp.

uint32 Image::Indeo::bitswap32 ( uint32 x )

Swap the order of the bytes in the passed value.

uint16 Image::Indeo::invertBits	(	uint16	val,
		int	nbits
	)

Reverse "nbits" bits of the value "val" and return the result in the least significant bits.
