Function rsmpeg::ffi::av_realloc_array [−][src]
pub unsafe extern "C" fn av_realloc_array(
ptr: *mut c_void,
nmemb: u32,
size: u32
) -> *mut c_void
Expand description
Allocate, reallocate, or free an array.
If ptr
is NULL
and nmemb
> 0, allocate a new block. If
nmemb
is zero, free the memory block pointed to by ptr
.
@param ptr Pointer to a memory block already allocated with
av_realloc() or NULL
@param nmemb Number of elements in the array
@param size Size of the single element of the array
@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 allocated memory is not guaranteed to be correctly aligned. @see av_reallocp_array()
