Function rsmpeg::ffi::av_realloc [−][src]
pub unsafe extern "C" fn av_realloc(ptr: *mut c_void, size: u32) -> *mut c_void
Expand description
Allocate, reallocate, or free a block of memory.
If ptr
is NULL
and size
> 0, allocate a new block. If size
is
zero, free the memory block pointed to by ptr
. Otherwise, expand or
shrink that block of memory according to size
.
@param ptr Pointer to a memory block already allocated with
av_realloc() or NULL
@param size Size in bytes of the memory block to be allocated or
reallocated
@return Pointer to a newly-reallocated block or NULL
if the block
cannot be reallocated or the function is used to free the memory block
@warning Unlike av_malloc(), the returned pointer is not guaranteed to be correctly aligned. @see av_fast_realloc() @see av_reallocp()
