Function notcurses_get 

pub unsafe extern "C" fn notcurses_get(
    n: *mut notcurses,
    ts: *const timespec,
    ni: *mut ncinput,
) -> u32

Read a UTF-32-encoded Unicode codepoint from input. This might only be part of a larger EGC. Provide a NULL ‘ts’ to block at length, and otherwise a timespec specifying an absolute deadline calculated using CLOCK_MONOTONIC. Returns a single Unicode code point, or a synthesized special key constant, or (uint32_t)-1 on error. Returns 0 on a timeout. If an event is processed, the return value is the ‘id’ field from that event. ‘ni’ may be NULL.
