pub unsafe extern "C" fn av_fifo_grow2(
f: *mut AVFifo,
inc: usize,
) -> c_int展开描述
Enlarge an AVFifo.
On success, the FIFO will be large enough to hold exactly inc + av_fifo_can_read() + av_fifo_can_write() elements. In case of failure, the old FIFO is kept unchanged.
@param f AVFifo to resize @param inc number of elements to allocate for, in addition to the current allocated size @return a non-negative number on success, a negative error code on failure
