Function rsmpeg::ffi::av_strlcpy

pub unsafe extern "C" fn av_strlcpy(
    dst: *mut i8, 
    src: *const i8, 
    size: u64
) -> u64

Copy the string src to dst, but no more than size - 1 bytes, and null-terminate dst.

This function is the same as BSD strlcpy().

@param dst destination buffer @param src source string @param size size of destination buffer @return the length of src

@warning since the return value is the length of src, src absolutely must be a properly 0-terminated string, otherwise this will read beyond the end of the buffer and possibly crash.
