Function rsmpeg::ffi::avio_get_str

pub unsafe extern "C" fn avio_get_str(
    pb: *mut AVIOContext, 
    maxlen: i32, 
    buf: *mut i8, 
    buflen: i32
) -> i32

Read a string from pb into buf. The reading will terminate when either a NULL character was encountered, maxlen bytes have been read, or nothing more can be read from pb. The result is guaranteed to be NULL-terminated, it will be truncated if buf is too small. Note that the string is not interpreted or validated in any way, it might get truncated in the middle of a sequence for multi-byte encodings.

@return number of bytes read (is always <= maxlen). If reading ends on EOF or error, the return value will be one more than bytes actually read.
