Function Documentation

attribute_deprecated void* ff_realloc_static	(	void *	ptr,
		unsigned int	size
	)

Same as av_mallocz_static(), but does a realloc.

Parameters:

[in]	ptr	The block of memory to reallocate.
[in]	size	The requested size.

Returns:

Block of memory of requested size.

Deprecated:

. Code which uses ff_realloc_static is broken/misdesigned and should correctly use static arrays
