Source 
pub unsafe extern "C" fn burn_os_alloc_buffer(
    amount: usize,
    flag: c_int,
) -> *mut c_void
Expand description

Allocate a memory area that is suitable for reading with a file descriptor opened by burn_os_open_track_src().

@param amount Number of bytes to allocate. This should be a multiple of the operating system’s i/o block size. 32 KB is guaranteed by libburn to be safe.

@param flag Bitfield for control purposes (unused yet, submit 0).

@return The address of the allocated memory, or NULL on failure. A non-NULL return value has finally to be disposed via burn_os_free_buffer().

@since 0.7.4
