结构体 AVIOInterruptCB 

#[repr(C)]
pub struct AVIOInterruptCB {
    pub callback: Option<unsafe extern "C" fn(arg1: *mut c_void) -> c_int>,
    pub opaque: *mut c_void,
}

Callback for checking whether to abort blocking functions. AVERROR_EXIT is returned in this case by the interrupted function. During blocking operations, callback is called with opaque as parameter. If the callback returns 1, the blocking operation will be aborted.

No members can be added to this struct without a major bump, if new elements have been added after this struct in AVFormatContext or AVIOContext.

Fields

callback: Option<unsafe extern "C" fn(arg1: *mut c_void) -> c_int>

opaque: *mut c_void
